Claims (8)

  1. Front wheels (2) and rear wheels (12) are positioned at least one at the front and one at the rear of the vehicle body (1A), A suspension device (3A, 13A) having a ride height adjustment function is positioned between at least one of the front wheels (2) and rear wheels (12) and a vehicle body component, A control device (23) controls the drive of actuators (43f, 43r) that extend and retract the suspension device (3A, 13A), A vehicle body angle detection device (34) for detecting the inclination angle (θ1) of the vehicle body (1A), A side stand (17) capable of supporting the vehicle body (1A) in an upright position tilted to one side, In a vehicle equipped with, The vehicle is equipped with a parking operation detection unit (37) that detects when the side stand (17) is used when the vehicle is parked. The control device (23) detects the parking operation detection unit (37) when it detects the operation, and when it detects the parking of the vehicle, it measures the inclination angle (θ1) of the vehicle body (1A) using the vehicle body angle detection device (34), and drives the actuators (43f, 43r) to extend or retract the suspension devices (3A, 13A) so that this inclination angle (θ1) approaches a specified target angle (θ2).
  2. The vehicle according to claim 1, wherein the control device (23) shortens the suspension devices (3A, 13A) when the inclination angle (θ1) is greater than the target angle (θ2), and extends the suspension devices (3A, 13A) when the inclination angle (θ1) is less than the target angle (θ2).
  3. (delete)
  4. The vehicle according to claim 1 or 2, wherein the parking operation detected by the parking operation detection unit (36, 37, 38) includes an operation that restricts the movement of the vehicle.
  5. The vehicle according to claim 1 or 2, wherein the control device (23) detects that the vehicle has not moved for a specified time after the vehicle's main switch (36) has been turned off, and detects that the vehicle is parked.
  6. At least one of the front wheels (2) and rear wheels (12) is equipped with a pair of left and right wheels (W1, W2), The suspension device (3A, 13A) comprises a pair of left and right cushion units (CS1, CS2) positioned between each of the left and right wheels (W1, W2) and the vehicle body components. As the pair of left and right cushion units (CS1, CS2) expand and contract, the pair of left and right wheels (W1, W2) can move up and down independently. The vehicle according to claim 1, wherein the control device (23) extends one of the left and right pair of cushion units (CS1, CS2), shortens the other, or both, so that the inclination angle (θ1) approaches the target angle (θ2).
  7. The vehicle is equipped with a parking control button (39) supported on the steering wheel (4a), The vehicle according to claim 1, wherein while the parking control button (39) is pressed, control is performed to bring the tilt angle (θ1) closer to a predetermined target angle (θ2).
  8. The seats (16a, 16b) are equipped with seating sensors. The vehicle according to claim 1, wherein when a user disembarks, control is performed to bring the tilt angle (θ1) closer to a predetermined target angle (θ2).

Description

This invention relates to a vehicle. This application claims priority based on Japanese Patent Application No. 2022-191429, filed in Japan on November 30, 2022, and the contents of that application are incorporated herein by reference. Conventionally, some vehicles have been designed to easily achieve a comfortable ride and good driving performance by electronically controlling the damping force and preload of the suspension system (see, for example, Patent Document 1). Japanese Patent Publication No. 2021-49812 This is a left side view of a motorcycle according to an embodiment of the present invention.This is a rear view showing the first example of parking the above-mentioned motorcycle, with the state before parking angle adjustment control shown on the left and the state after parking angle adjustment control shown on the right.This is a rear view showing a second example of the above-mentioned motorcycle being parked, with the left side showing the state before parking angle adjustment control and the right side showing the state after parking angle adjustment control.This is a rear view showing a third example of the above-mentioned motorcycle being parked, with the left side showing the state before parking angle adjustment control and the right side showing the state after parking angle adjustment control.This flowchart shows the process performed by the control device in the above parking angle adjustment control.Figure 5 is a flowchart showing the process of adjusting the parking angle.This is a block diagram of the control system for the above-mentioned motorcycle.This is a schematic diagram of the suspension control device for the above-mentioned motorcycle.This is a rear view showing an example of parking angle adjustment control for a vehicle equipped with a pair of left and right wheels.This is a left side view illustrating an example of parking angle adjustment control for a vehicle equipped with suspension devices on both the front and rear wheels. Embodiments of the present invention will be described below with reference to the drawings. Unless otherwise specified, directions such as front, rear, left, and right in the following description are the same as those of the vehicle described below. In the drawings used in the following description, arrows FR indicating the front of the vehicle, LH indicating the left side of the vehicle, UP indicating the top of the vehicle, and CL indicating the center of the vehicle are shown in appropriate places. <Entire vehicle> Figure 1 shows a motorcycle 1 as an example of a vehicle employing a parking angle control device according to an embodiment of the present invention. Motorcycle 1 is an example of a saddle-type vehicle in which the rider (user) straddles the vehicle body. Motorcycle 1 turns by swaying (banking) the vehicle body in the left-right direction (roll direction) based on the contact points of the front and rear wheels. The vehicle of the present invention is not limited to vehicles that turn by banking the vehicle body, but also includes vehicles that turn by steering the steering wheels without banking the vehicle body. It also includes vehicles equipped with an electric motor as the prime mover. The front wheel 2 of the motorcycle 1 is supported by the lower ends of a pair of left and right front forks (telescopic forks) 3. The left and right front forks 3 are supported by the head pipe 6 at the front end of the vehicle frame 5 via a steering stem 4. A handlebar (steering handle) 4a for steering the front wheel is attached to the upper part of the steering stem 4. The pair of left and right front forks 3 constitute the front suspension system 3A of the motorcycle 1. The vehicle frame 5 comprises a head pipe 6, a pair of left and right main frames 7 that branch off to the left and right behind the head pipe 6 and extend diagonally downward and rearward, a pair of left and right pivot frames 8 that extend downward from the rear ends of the left and right main frames 7, and a rear frame 9 that extends behind the left and right pivot frames 8. A fuel tank 15 is supported above the left and right main frames 7, and front and rear seats 16a and 16b are supported above the rear frame 9. The power unit P is supported below the left and right main frames 7 and in front of the left and right pivot frames 8. The power unit P is an integrated unit including an engine (e.g., an internal combustion engine) E and a transmission. A foldable side stand 17 is provided at the lower end of the left pivot frame 8, capable of supporting the vehicle body 1A in an upright position tilted to the left. The front ends of the swingarm 11 are supported by the left and right pivot frames 8. A single rear wheel 12 is supported by the rear end of the swingarm 11. A single rear cushion unit 13 is interposed between the front of the swingarm 11 and the vehicle frame 5. The rear cushion unit 13 constitutes the rear suspension system 13A of the motorcycle 1.
