Abstract

The invention discloses a method, device and system for judging the steering position of a vehicle lever based on a Hall device, belonging to the field of driving assistance systems. and Hall device, installed in the structure, can adjust the orientation) and magnet, the main control board is located on the central axis under the steering wheel, two Hall devices are installed on the left and right ends of the main control board, and the front of the Hall device corresponds to the lever respectively When turning left and right to the position of the lever, the magnet is installed on the lever; when the lever is turned, because the magnet on the lever is close to or far away from the Hall device, different voltage values ​​will be generated, and the corresponding voltage values ​​will be sent to the control unit , the control unit performs difference calculation on the obtained voltage value to judge the steering state of the lever. The present invention adopts a Hall device to judge the state of the steering lever. As long as the lever is rotated, there will be a voltage difference; the threshold value can be adjusted adaptively to achieve the optimal recognition effect.

Description

technical field [0001] The invention belongs to the field of driving assistance systems, and more specifically relates to a method, device and system for judging the steering position of a vehicle lever based on a Hall device. Background technique [0002] Lane Departure Warning System (Lane Departure Warning System, LDWS) is an auxiliary driving system that sends out an alarm when the driver deviates from the lane unconsciously. The basis for judging whether the driver changes lanes consciously is whether the driver turns on the turn signal before the car deviates from the lane. The way to obtain the steering signal can be to judge the state of the steering lever through an additional sensor. [0003] Patent CN106672075A uses an acceleration sensor to judge the state of the steering lever, such as figure 1 As shown, the vehicle steering state detection device is installed on the steering lever of the car, including an acceleration sensor, a button, a power supply unit, a w...
