A method and system for vehicle parallel assisted driving

Abstract

The embodiments of the invention relate to a vehicle parallel assisting driving method and system. The vehicle parallel assisting driving method comprises the steps: firstly, the vehicle state and environment information surrounding a vehicle are obtained through a vehicle-mounted sensor, wherein the vehicle state and the environment information mainly include the vehicle speed and position and speed information of surrounding vehicles; then a vehicle-mounted arithmetic unit calculates the acceleration and deceleration demands of avoiding the parallel state of the vehicle according to the obtained vehicle and environment information; and finally, a vehicle control unit receives the acceleration and deceleration demands and then actively controls a vehicle accelerator and brake system to adjust the vehicle speed, and thus the parallel assisting function is achieved. Thus, in the parallel state, the vehicle speed can be actively adjusted, then the vehicle is staggered with the vehicles on adjacent lanes in the longitudinal direction, the vehicle can be prevented from entering into the lone-time parallel state, driving safety is improved, and human driving habits are met.

Description

technical field [0001] The present invention relates to the field of automatic driving, in particular to a vehicle parallel assisted driving method and system. Background technique [0002] With the rapid growth of the vehicle market in China, driver assistance systems have been extensively studied. Among them, some longitudinal advanced driving assistance systems have been commercialized, reducing the driver's load to a certain extent. [0003] One scenario in lane keeping is that there are vehicles running parallel to the own vehicle in the adjacent lane, and vehicles paralleling each other for a long time is a relatively risky driving state. Once an emergency occurs, it may lead to serious traffic accidents. Generally, human drivers will try to avoid it. open this situation. In order to improve driving safety, a vehicle parallel driving assistance system is needed, which can adjust the vehicle speed in time when vehicles parallel for a long time occur or are about to oc...

AI Technical Summary

Problems solved by technology

[0005] The above-mentioned longitudinal advanced driving assistance system only pays attention to the position speed of the vehicle in front and the expected speed of the ego vehicle, and does not consider the state of the vehicle in the adjacent lane. Therefore, when the ego vehicle is in a parallel state, it does not have the active speed adjustment function, which has potential safety hazards and reduces the riding experience.
