Abstract: A fault diagnosis method and a fault diagnosis apparatus for a vehicle speed measurement apparatus. The method includes: obtaining a first vehicle speed measured by the speed measurement apparatus; obtaining reference information of a static reference object at N moments, where N is an integer greater than 1, and the reference information includes information about a location relationship of the static reference object relative to a vehicle in which the speed measurement apparatus is located at each of the N moments; calculating a second vehicle speed based on the reference information; and determining, based on the first vehicle speed and the second vehicle speed, whether the speed measurement apparatus is faulty.

Abstract: A wireless charging parking space recommendation method is disclosed. The method includes: When a vehicle enters a parking lot, vehicle information is reported to the parking lot. A parking lot server compares and matches the vehicle information with pre-stored wireless charging parking space information, and comprehensively determines, based on the vehicle information, whether an available charging parking space exists in the current parking lot, selects an optimal parking space, and pushes a path to the optimal parking space and a parking manner to a vehicular device. A server, a vehicular device, a system, a vehicle, a computer-readable storage medium, a computer program product, a control unit, and a chip are also disclosed.

Abstract: A pedal fault diagnosis method and apparatus for a vehicle are provided, including: detecting whether a driver seat is in an unmanned state; collecting an actual zero position voltage of a pedal when the driver seat is in the unmanned state; and then determining, based on the actual zero position voltage, whether a zero position fault exists on the pedal. The apparatus may update a set value of a zero position voltage in a vehicle controller based on the actual zero position voltage that is collected when the driver seat is in the unmanned state, and may be applied to the fields of assisted driving and automatic driving. Vehicle control safety can be improved by using the actual zero position voltage that is collected when the driver seat is in the unmanned state.
