Embodiment Construction

[0034] Those skilled in the art understand that after the shift lever position of the car is found to be invalid, the prior art is still limited to adjusting the state of the car according to the default value, for example, after the shift lever position of the car is found to be invalid, the shift lever position For neutral processing. However, there are certain risks in the above scheme. For example, when the position of the shift lever suddenly fails when the car is running at high speed, if the position of the shift lever of the car is set to neutral according to the default value, it is very easy to cause the power of the car to suddenly change. Lost, seriously endangering the safety of life and property of users.

[0035] In order to solve the above technical problems, the technical solution of the present invention judges whether the shift lever position signal acquired this time is valid according to the feature detection information in the first processed signal, and ...

Abstract

The invention relates to a method, a device and a system for detecting failure of gear lever location. The method comprises the following steps of receiving a first processing signal sent by signal collection equipment, wherein the first processing signal comprises a gear lever location signal and feature detection information, and the feature detection information is used for representing the state of the signal collection equipment or the state of the gear lever location signal; according to the feature detection information, judging whether the gear lever location signal is valid or not; when a judging result indicates that the gear lever location signal is invalid, adjusting the state of an automobile according to the speed of the automobile. By adopting the technical scheme, the method has the advantages that the failure of the gear lever location of the automobile can be timely and effectively detected; after the failure of the gear lever location is determined, the influence byautomobile speed is considered in a processing plan, so as to protect the life and property safety of a user.

Description

technical field [0001] The invention relates to the field of functional safety of automobile systems, in particular to a method, device and system for detecting and processing failure of a shift lever position. Background technique [0002] With the large-scale development of the automobile industry, automobiles have become inseparable from people's lives, and more and more people have begun to use automobiles as the preferred means of transportation for daily travel. In the process of driving a car, the driver often controls the car to enter different driving states by switching the gear of the shift lever, such as parking, forward, backward, etc. For the vehicle controller of the car, it is through The position of the shift lever is used to judge the driver's driving intention. However, if the position of the shift lever fails, for example, the shift lever position signal used to indicate the position of the shift lever fails, it will cause the vehicle controller to misre...
