Embodiment Construction

[0039] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0040] The embodiments of the present invention aim at the lack of diagnosis strategy for the angle signal output by the angle sensor in the prior art, and when the angle signal is unreliable, the electric power steering system controller still controls the steering of the vehicle according to the angle signal, resulting in abnormal steering To solve the problem, a steering control method, device, electric power steering system controller and automobile are provided, so that when the angle signal is unreliable, the driver is reminded to drive carefully, and the safety and reliability of the automobile are improved.

[0041] like figure 1 As shown, an embodiment of the present invention provides a steering control method, including:

[0042] Step 11, acq...

Abstract

The invention provides a steering control method and device, an electric power assisting steering system controller and an automobile, and relates to the technical field of vehicle control. The steering control method comprises the following steps: obtaining an angle signal acquired by a steering angle sensor used for acquiring a steering angle of a steering wheel of a vehicle; judging whether theangle signal is a trusted signal; controlling the steering of the vehicle according to the angle signal when it is determined that the angle signal is the trusted signal; sending out an alarm promptwhen it is determined that the angle signal is an untrusted signal. The method judges the credibility of the angle signal outputted from the steering angle sensor and sends out an alarm prompt when the angle signal is not credible, avoids the steering abnormality of the whole vehicle due to the unreliable angle signal outputted from the steering angle sensor, and improves the safety and reliability of the automobile.

Description

technical field [0001] The invention belongs to the technical field of complete vehicle control, and in particular relates to a steering control method and device, a controller of an electric power steering system and an automobile. Background technique [0002] In the prior art, the electric power steering system of a car does not have a diagnostic strategy for the reliability of the angle signal sent by the angle sensor. For example, the electric power steering system only uses the angle signal as its active verification function and end protection function. A necessary condition of the angle signal, but it does not diagnose the reliability of the angle signal itself, that is, whether it is reliable or not usable, so that even if the angle signal is not credible, the electric power steering system controller is still based on the angle signal Control the steering of the vehicle, which is prone to abnormal steering, which reduces the safety and reliability of the car.
