Abstract

[Problem] In a vehicle equipped with manual and automatic modes, the range at which the switch occurs when switching from manual mode to automatic mode needs to be set. [Solution] This disclosure relates to an automobile capable of switching between a manual mode in which the driver performs gear shifting operations and an automatic mode in which the driver does not perform gear shifting operations. The automobile comprises a manual mode shift selector used for selecting the gear position in manual mode and an automatic mode shift selector used for selecting the range in automatic mode. When the first condition is met, and the mode is switched from manual mode to automatic mode, the range is set to a non-driving range. [Selection Diagram] Figure 5

Description

This disclosure relates to an automobile capable of switching between a manual mode, in which the driver manually operates the gear shift, and an automatic mode, in which the driver does not need to operate the gear shift. Patent Document 1 discloses an electric vehicle that simulates the manual gear shifting operation of a manual transmission (MT) vehicle. This electric vehicle is configured to allow switching between an MT driving mode, in which the driver manually shifts gears, and an EV driving mode, in which the vehicle operates as a typical EV without manual gear shifting. Japanese Patent Publication No. 2022-030862 This figure shows the configuration of an electric vehicle according to an embodiment of this disclosure.This diagram shows the configuration of a control device related to the driving control of an electric vehicle.This figure shows an example of the configuration of the shift selector in the first embodiment.This is a table showing the range selected in the second embodiment.This is a table showing the range selected in the third embodiment.This figure shows an example of the configuration of the shift selector in the fourth embodiment.This figure shows an example of the configuration of the shift selector in the fifth embodiment. 1. Configuration of the Electric Vehicle's Power System Figure 1 is a schematic diagram showing the configuration of an electric vehicle 100 according to an embodiment of this disclosure. First, the configuration of the electric vehicle 100's power system will be explained with reference to Figure 1. The electric vehicle 100 is equipped with two electric motors (M) 4F and 4R at the front and rear as power sources for propulsion. The electric motors 4F and 4R are, for example, three-phase AC motors. The front electric motor 4F is connected to the front drive shaft 5F, which drives the front wheel 6F. The rear electric motor 4R is connected to the rear drive shaft 5R, which drives the rear wheel 6R. The front wheel 6F is suspended by an independently electronically controlled front suspension 7F. The rear wheel 6R is suspended by an independently electronically controlled rear suspension 7R. The front electric motor 4F and the rear electric motor 4R are each fitted with inverters (INVs) 3F and 3R, respectively. The front inverter 3F and the rear inverter 3R are each connected to the battery (BATT) 2. Battery 2 stores the electrical energy to drive the electric motors 4F and 4R. In other words, the electric vehicle 100 is a battery electric vehicle (BEV) that runs on the electrical energy stored in battery 2. Inverters 3F and 3R are, for example, voltage-type inverters that control the torque of the electric motors 4F and 4R by PWM control. 2. Control System and Control Modes of Electric Vehicles Next, the configuration of the control system of the electric vehicle 100 will be explained with reference to Figure 1. The electric vehicle 100 is equipped with a control device 101. The control device 101 is connected to sensors and controlled devices mounted on the electric vehicle 100 via an in-vehicle network. The control device 101 includes at least a processor (processing circuit) 102 and a memory 103. The memory 103 includes RAM for temporarily recording data and ROM for storing programs 104 executable by the processor 102 and various data 105 related to the program. The program 104 consists of multiple instructions. The processor 102 reads the program 104 and data 105 from the memory 103, executes them, and generates control signals based on signals acquired from the sensors. The control device 101 may have one or more processors 102 and memory 103. The control device 101 performs various controls on the electric vehicle 100. One or more programs 104 are read from the memory 103 and executed by the processor 102, thereby enabling the control device 101 to control the electric vehicle 100. The control of the electric vehicle 100 by the control device 101 includes driving control, which controls the movement of the electric vehicle 100. In driving control, the control device 101 can control the electric vehicle 100 in multiple control modes. The control modes of the electric vehicle 100 that can be selected by the control device 101 include EV mode and MT mode. EV mode is a mode in which the electric motors 4F and 4R are controlled to drive with normal torque characteristics. MT mode is a control mode for operating the electric vehicle 100 like a manual transmission (MT) vehicle. In MT mode, the driver can use the shift selector 24 (described later) to perform a virtual gear shift operation that simulates the gear shift operation (shift operation) of an MT vehicle, and select a virtual gear position (gear step/shift position). The electric vehicle 100 is equipped with a human-machine interface (HMI) 20 as an interface with the driver. The HMI 20 has a touch panel display. The HMI 20 displays information on the touch panel display and accepts input from the driver v
