Abstract

The invention relates to an integrated electrical control braking system with a drive assistance function, comprising an information acquisition device, a controller and a brake actuator; wherein, the controller includes a microprocessor provided with a control policy computing module; the control policy computing module in the microprocessor judges and calculates the current state of vehicle according to the current working state information of the vehicle and barrier information in front of the vehicle which are acquired by the information acquisition device, so that the corresponding controlled quantity can be worked out and is transmitted to the brake actuator, and the brake actuator implements the corresponding automatic brake on the vehicle according to the controlled quantity; when the microprocessor receives a manual brake signal, the control policy computing module in the microprocessor stops the work of calculating the controlled quantity. The invention is safe, and has complete functions, high control accuracy and low cost, thus being suitable for popularization and application.

Description

technical field [0001] The invention relates to the technical field of vehicle safety, in particular to an integrated electric brake system with driving assistance function. Background technique [0002] Traffic accidents have caused great economic losses and casualties, and are serious problems faced by modern society. Due to the limitations of the driver's own physiology or driving experience, the driver will often experience driving operations such as fatigue, negligence, and misjudgment, which will lead to traffic accidents. According to relevant statistics, the number of traffic accidents caused by the above-mentioned faults accounts for the total More than 90% of the number of traffic accidents. In view of the above facts, reducing the driver's labor intensity and expanding the driver's perception range to improve the driver's safe driving ability and reduce the incidence of traffic accidents caused by negligence have become the primary goals of research by automobile...
