Problems solved by technology

[0005] In view of this, the present invention aims to propose a vehicle subsystem control method to solve the problem in the prior art that the control of the vehicle subsystem depends on the driver's operation on the hardware selection switch to switch the driving mode, and the selected driving The mode may also not be related to the actual driving state of the vehicle, resulting in technical problems of poor driving experience

Embodiment Construction

[0042] It should be noted that, in the case of no conflict, the embodiments and features in the embodiments of the present invention can be combined with each other.

[0043] In addition, the surface MU (Medium Utilization) mentioned in the embodiments of the present invention refers to the medium utilization rate of the driving surface. A more specific explanation for the surface MU can be: based on the surface MU, a certain driving surface can be determined With respect to the range of vehicle operating parameters under normal conditions, in other words, the driving surface medium utilization is indicative of the range of parameters related to said vehicle operating parameters within which the vehicle can be safely operated. For example, the surface MU can refer to the longitudinal acceleration a x and lateral acceleration a y A finite range of , within which the vehicle can safely operate, for example in a graph (not shown) with longitudinal and lateral acceleration as ort...

Abstract

The invention relates to the technical field of intelligent vehicles, and provides a vehicle subsystem control method and a vehicle. The vehicle subsystem control method comprises the following steps:obtaining vehicle operating parameters about the vehicle operating in a first time; determining driver intent based on the vehicle operating parameters; selecting a first vehicle driving mode from aplurality of preset vehicle driving modes according to the driver's intent; outputting the first vehicle driving mode to set an operating state of at least one subsystem in a vehicle chassis. As such,on that one hand, the dependence on the hardware selection switch adopt in the prior art is eliminated, and the vehicle drive mode is automatically switched; On the other hand, in the process of switching the driving mode of the vehicle, the vehicle working parameters generated by the actual driving of the vehicle are taken into account, so that the driving mode of the automatic switching is moresuitable for the actual operating state of the vehicle, thereby optimizing the driving experience of the vehicle driver.

Description

technical field [0001] The invention relates to the technical field of intelligent vehicles, in particular to a method for controlling a vehicle subsystem. Background technique [0002] Vehicles are often equipped with switches to allow the driver to select a preferred driving mode such as standard, economy, sport, etc. In many cases, the driver selects a specific driving mode setting, but his / her actual driving is not necessarily related to his selected driving mode, at which point the driver feels that the vehicle is not responding appropriately to his / her driving needs . [0003] Currently, many vehicles are equipped with a driver selector switch to allow the driver to choose between several predetermined driving modes (ie standard, sport, etc.). As the number of controllable systems increases, the driver will be faced with more and more choices as to which configuration modes to choose to optimize the settings of the chassis subsystems for actual driving behavior. Thi...
