Abstract

The invention relates to a method and a system for improving brake delay of an intelligent driving vehicle. The method comprises the following steps that the braking environment of the intelligent driving vehicle is detected; judging whether an automatic braking mode is started or not according to the braking environment; under the condition that the automatic braking mode is started, a reverse towing torque request is sent to a motor, and the intelligent driving vehicle is controlled to conduct reverse towing braking; and in the case where the automatic braking mode is activated, simultaneously sending a braking request and activating the mechanical braking. The system comprises an ADAS module, a vehicle-mounted controller, an electronic braking control module and a motor. The vehicle-mounted controller is configured to send a reverse towing torque request to the motor and control the intelligent driving vehicle to perform reverse towing braking under the condition that an automatic braking mode is started; in the case where the automatic braking mode is activated, simultaneously sending a braking request and activating the mechanical braking.

Description

technical field [0001] The invention relates to the field of complete vehicle systems equipped with quick-response braking capabilities. Specifically, the present invention relates to a system and method for improving braking delay of an intelligent driving vehicle. Background technique [0002] Contemporary vehicle technology is evolving rapidly. Many countries in the world have formulated a number of relevant policies on intelligent driving to promote the integration of intelligent driving vehicles with existing transportation systems and encourage the development of intelligent driving technology. As an important part of intelligent driving Level 2, the automatic emergency braking (AEB) system plays a huge role in preventing vehicle collisions and protecting pedestrians and drivers. With the rapid development of intelligent driving technology, more and more control rights of vehicles will be handed over to the on-board control unit in the future. Those functions that re...
