Problems solved by technology

However, the current braking energy recovery system does not give a reminder to the rear vehicle during the recovery process of the vehicle's coasting energy. If the recovery torque is large, the braking effect is obvious, and there is a hidden danger of rear-end collision when the driver of the vehicle coming from the rear does not receive a reminder. Similar to the danger posed by a failed rear brake light

Abstract

The invention provides a vehicle control method. A vehicle comprises a power battery and a motor used for driving the vehicle. The vehicle control method comprises the following steps that the accelerator pedal signal and the brake pedal signal of the vehicle are acquired; whether the vehicle is braked or not is judged according to the accelerator pedal signal; if the vehicle is braked, the braking mode of the vehicle is further judged according to the brake pedal signal; if the vehicle is in a slide braking mode, the practical energy recovery moment of the vehicle is acquired; if the practical energy recovery moment is larger than the preset energy recovery moment, a brake taillight of the vehicle is controlled to be lightened to prompt vehicles behind the vehicle. The vehicle control method can improve the driving safety of vehicles with the brake energy recovery function. The invention further provides a vehicle control system.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a vehicle control method and system. Background technique [0002] With the rapid development of new energy vehicle technology, more and more new energy vehicles are driving on the road. Regardless of hybrid vehicles or pure electric vehicles, they generally have the function of braking energy recovery. Braking energy recovery can improve the energy efficiency of the vehicle. However, the current braking energy recovery system does not prompt the rear vehicle during the recovery process of the vehicle's coasting energy. If the recovery torque is large, the braking effect is obvious, and there is a hidden danger of rear-end collision when the driver of the vehicle coming from the rear does not receive the prompt. Similar to the danger posed by a failed rear brake light. Contents of the invention [0003] The present invention aims at solving one of the techni...
