The invention relates to a slope brake pressure determining method and system. The method includes: a pre-braking slope estimated value is determined according to a specified cycle, where a current pre-braking slope estimated value is determined and is used as a first slope estimated value a, and a pre-braking slope estimated value of a previous cycle that is latched prior to the establishment of brake pressure is used as a second slope estimated value a; an instantaneous vehicle speed vprior to the establishment of the brake pressure is latched, a vehicle traveling distance land time tare accumulated, and an in-braking slope estimated value ais determined based on the instantaneous vehicle speed v, the vehicle traveling distance l, and the time t; and pre-braking pressure pand in-braking pressure pare determined based on the second slope estimated value aand a third slope estimated value a, respectively, initial brake pressure pis determined based on the pre-braking pressure pand the in-braking pressure p, and final brake pressure pis determined based on the initial brake pressure p. According to the invention, the brake pressure can be accurately determined.

Slope brake pressure determining method and determining system, and vehicle

The disclosure relates to the field of vehicle technologies, and specifically, to a vehicle control method and system, a vehicle, a control apparatus, a vehicle-mounted device, and a computer-readable storage medium. The disclosure aims to solve the following technical problem: Since a distinction between understeering and oversteering conditions is not taken into consideration when increasing the engine torque, there is still room for improvement in a formulated engine torque increasing strategy. For this purpose, the disclosure provides a vehicle control method and system, a vehicle, a control apparatus, a vehicle-mounted device, and a computer-readable storage medium, where the control method includes: when an abnormal state occurs in a vehicle in a steering condition, determining whether the current abnormal state is understeering or oversteering; and adjusting torque of the vehicle based on a determining result and a torque amount adjustment mechanism predetermined for the current abnormal state. Through such settings, a feasible torque adjustment strategy can be provided for each of the understeering and oversteering conditions.

Vehicle and control method thereof, control apparatus, vehicle-mounted device and medium

The disclosure relates to a vehicle control method. The vehicle control method includes: receiving a first control instruction; sending a first output signal based on the first control instruction, where the first output signal is used to instruct a hydraulic parking system to start pressure build-up; and sending a second output signal upon the hydraulic parking system reaching a predetermined first state, where the second output signal is used to instruct an electronic parking system to start to be pulled up or released. The disclosure further relates to a vehicle control device, a computer-readable storage medium, and a vehicle. According to the vehicle control solution provided in the disclosure, a hydraulic parking system and an electronic parking system are controlled in a coupled manner in vehicle starting and stopping conditions, thereby providing a user with highly comfortable, reliable, and safe vehicle starting and stopping experience.

Vehicle control method and device, storage medium, and vehicle

This application relates to a vehicle control method and system, a vehicle, and a storage medium. The vehicle control method includes: when a braking system fails, activating a backup braking system, the backup braking system decelerating a vehicle by controlling a regenerative motor; when a steering system fails, implementing transverse control over the vehicle by controlling the braking system; and when a parking system fails, implementing parking by controlling a motor and the braking system to work alternately. According to this method, safety control over the vehicle can be implemented when the original braking system, steering system, or parking system fails.
