Abstract

The invention relates to a method for controlling a vehicle by means of a central motion controller, wherein the central motion controller detects at least one motion request and vehicle dynamic parameters and, based on the motion request and the vehicle dynamic parameters, determines control variables for vehicle motion actuators and sends them to the actuators. To improve the driving experience, the central motion controller also controls user experience functions, devices, and/or applications.

Description

The invention relates to a method for controlling a vehicle by means of a central motion control system, wherein the central motion control system detects at least one motion request and vehicle dynamic parameters and determines control parameters for vehicle motion actuators based on the motion request and the vehicle dynamic parameters and sends them to the actuators. While in the past many actuators had their own control units, each receiving a separate request as a control variable for the actuators, modern vehicle motion control systems are equipped with a central control unit. This unit determines, based on all inputs, how and by which actuators the request can best be implemented in the current driving situation. In existing systems, user experience (UX) elements, i.e., user experience functionalities, remain unaffected, and their potential for improving the driving experience is thus untapped. However, it is particularly important on long journeys that the driver is offered a high level of comfort through these functionalities. It is therefore the object of the present invention to optimally utilize a central motion control system. The problem is solved by a method according to claim 1 for controlling a vehicle by means of a central motion control unit, wherein the central motion control unit detects at least one motion request and vehicle dynamic parameters and, based on the motion request and the vehicle dynamic parameters, determines control variables for vehicle motion actuators and sends them to the actuators, wherein the central motion control unit also controls user experience functions, devices, and/or applications. Thus, the entire user experience of the driver is controlled by a central unit. Furthermore, this connection of the UX units with the central control unit creates a way for the driver and passengers to harmonize the driving experiences, for example, by adapting sound and light effects, seating positions, and displays in the dashboard or VR devices to the current and future movement of the vehicle. The user experience functions, devices, and/or applications are therefore precisely those that go beyond simple warning displays and are already active during normal driving operation. In a preferred embodiment of the invention, the motion request comprises vehicle setpoints, a target trajectory, vehicle movement specifications, and/or driver specifications. The motion request can therefore be transmitted to the central control unit in various ways, which processes it and decides which actuator is controlled and how. The central motion control unit thus has all the relevant information available to optimally control the user experience functions. In a further preferred embodiment of the invention, the vehicle motion actuators comprise at least one drive unit, one steering unit, and one brake unit. This allows them to control the main actuators of a vehicle and select user experience functions according to the actuator specifications. In a further preferred embodiment of the invention, the vehicle motion actuators further comprise at least one damper unit, one aerodynamic unit, and/or one differential unit. Each additional unit allows for more comprehensive control of the vehicle and enables the user experience functions to be aligned with the specifications for these actuators. In a further preferred embodiment of the invention, the user experience features, devices and/or applications include a dashboard display selection, interior lighting, engine sounds, and/or a seating position. In another preferred embodiment of the invention, the user experience features, devices and/or applications include a virtual reality unit for passengers. In a further preferred embodiment of the invention, the central motion control is executed on a central hardware unit of the vehicle. This can preferably be a high-performance computer (HPC) of the vehicle. User experience functions within the meaning of the invention are, in particular, those that go beyond the mere display of warnings. In a further preferred embodiment of the invention, the central motion controller transmits signals, states, and/or operating modes to the user experience functions, devices, and/or applications. For this purpose, these can be connected, for example, via a bus connection. In a further preferred embodiment of the invention, the central motion control system controls the user experience functions, devices, and/or applications based on current or future driving situations. By controlling the system based on future driving situations, the driver and/or passenger can prepare for them in advance. In a further preferred embodiment of the invention, the vehicle dynamics parameters include at least data from wheel speed sensors, an IMU (sensor cluster with multiple acceleration and/or yaw rate sensors), a camera, a radar, a lidar, GPS and/or ultrasonic sensors. In a further preferred embodiment of the invention, the central motion
