Abstract

The invention provides a gear identification system for preventing incorrect manipulation on an electric automobile, and the gear identification system comprises a gear switching device, a gear signal identification device, an MCU (Micro-programmed Control Unit), a driving motor and a speed reducer, wherein the gear switching device is connected with the gear signal identification device; the gear signal identification device is connected with the MCU through a CAN (Controller Area Network) bus; the MCU controls the driving motor to work; and the driving motor is connected with the speed reducer. The invention further provides a gear identification method for preventing the incorrect manipulation on the electric automobile. According to the method, if a driver carelessly does the incorrect manipulation in a vehicle driving process, a vehicle still moves forwards in an intended direction of the driver, so as to prevent the vehicle from suddenly reducing the speed and causing accidents.

Description

【Technical field】 [0001] The invention relates to the technical field of electric vehicles, in particular to a gear recognition method for preventing misoperation on electric vehicles. 【Background technique】 [0002] Traditionally, the position of the gear lever of the vehicle is identified, and the automatic transmission control system is generally used. Existing electric vehicle gears do not use a mechanical shift mode, but are controlled by a vehicle controller. The existing gear identification device and method of an electric vehicle only considers identifying the gear at which the current switching gear shift device is located, and outputs the gear signal to the vehicle, so that the vehicle travels according to the gear signal. It does not take into account that if a misoperation occurs during the driving of the electric vehicle (for example, the gear is directly shifted from the forward gear to the reverse gear or directly from the reverse gear to the forward gear), i...
