Vehicle steering detection system and method based on ADAS technology

Abstract

The invention discloses a vehicle steering detection system based on the ADAS technology. The vehicle steering detection system comprises a shifting lever state detector and an ADAS host; the shifting lever state detector is used for generating active steering data and sending the data out when the shifting lever state detector detects that the vehicle steers, and a shifting lever is shifted; the ADAS host is used for receiving the active steering data and being configured with an LDW module; the LDW module is used for obtaining lane departure data and processing the lane departure data and the active steering data; when the LDW module only obtains the lane departure data, an alarming signal is output; and when the LDW module obtains the lane departure data and the active steering data simultaneously, no alarming signal is output. According to the vehicle steering detection system, active lane changing or dangerous lane changing of the vehicle can be accurately judged, false alarming is effectively prevented, and meanwhile the automobile line does not need to be disassembled, so that the mounting difficulty and cost are greatly reduced, and the safety hidden trouble is eliminated.

Description

technical field [0001] The invention relates to an automobile driving assistance system, in particular to a vehicle steering detection system based on ADAS technology. Background technique [0002] The Advanced Driving Assistant System (ADAS) is a system used to collect relevant data during the driving process of the car, and then realize functions such as assisted driving and improved safety. Its representative company is Mobileye in Israel. The so-called assisted driving refers to providing warning functions such as lane departure warning (Lane Departure Warning, LDW), forward collision warning (ForwardCollision Warning, FCW) and pedestrian collision warning during driving. In terms of LDW lane departure, cameras are usually used to monitor whether the vehicle deviates from the lane line. There are two possible scenarios for lane departure: one is that the driver actively changes lanes by turning on the turn signal, which is considered a safe behavior at this time; the oth...

Problems solved by technology

[0003] At present, domestic driving recorders with ADAS functions almost use the pseudo-LDW algorithm, which can only obtain the lane departure situation. LDW alarm will occur when the car changes lanes, there are serious false alarms, and it is difficult to popularize and apply

Regarding how to determine whether it is a normal lane change behavior in the ADAS system, Mobileye’s solution is to dismantle the car parts, break the wire to connect to the CAN bus inside the vehicle, and then judge whether it is the driver’s active behavior according to the status of the turn signal. The method has the following defects: First, the electronic circuit must be disassembled, which is not only difficult to install, but also has a high installation cost; secondly, the unauthorized connection of the car circuit is likely to cause crosstalk between electrical signals, and there are potential safety hazards
