Problems solved by technology

For a pure electric vehicle with a manual transmission, when the driver operates the vehicle on a slope, there is a short-term transition process in which the vehicle has no mechanical braking force. In slope conditions, the vehicle will slide backwards, which may e

Abstract

The invention relates to a blade electric vehicle motor assisting hill parking and hill starting control system. The system comprises a drive motor, a motor rotation speed sensor and a motor controller. A motor drive control signal output interface of the motor controller is connected with a control signal input interface of the drive motor. The motor rotation speed sensor is used for monitoring the motor rotation speed of the drive motor. A drive motor rotation speed data output interface of the motor rotation speed sensor is connected with a drive motor rotation speed data input interface of the motor controller. The motor controller is further provided with a clutch pedal status signal communication interface, a brake pedal status signal communication interface, an accelerator pedal status signal communication interface and a gearbox gear status signal communication interface. By the adoption of the system and method, the hill sliding phenomenon is effectively reduced, and the traveling safety of a vehicle is improved.

Description

Technical field [0001] The invention relates to the technical field of pure electric vehicle control, in particular to a pure electric vehicle motor-assisted parking and ramp start control system and method. Background technique [0002] For pure electric vehicles, the drive motor is the only power source, which provides power to realize the vehicle's driving. When the vehicle is running, it is necessary to park the vehicle on the ramp or start from the ramp. For pure electric vehicles with manual gears, when the driver operates the vehicle on a ramp, there is a short transition process in which the vehicle has no mechanical braking force. In this process, the vehicle moves due to gravity, especially for upper In slope conditions, the vehicle will slip backwards, which is likely to cause safety accidents. The existing publicly disclosed methods for starting a pure electric vehicle on a ramp are mainly for direct drive or automatic transmission vehicles, and no mention is made o...
