Electrical automobile control system and control method

Abstract

The invention provides an electrical automobile control system, which comprises a motor, a motor controller, a transmission, a transmission controller and an integral automobile controller, wherein the motor controller is connected with the motor, and is used for controlling the motor, the transmission is connected with the motor, the transmission controller is used for controlling the transmission and carrying out communication with the motor controller, and the integral automobile controller is respectively connected with the motor controller and the transmission controller, and is used for sending control commands to the motor controller and the transmission controller, and receiving feedback signals from the motor controller and the transmission controller. The control system provided by the embodiment of the invention has the advantages that the structure is simple, and the cost is low; the speed regulating precision of the transmission is high, and the response speed is high. The invention also provides a control method.

Description

technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to an electric vehicle control system and control method. Background technique [0002] Compared with conventional vehicles, electric vehicles have excellent power performance, economy and emission performance, and are currently one of the key points in the research and development of new vehicle power transmission systems at home and abroad, and have received widespread attention from users and the market. In the field of electric passenger vehicles, in order to give full play to the high-speed performance of the motor, most currently use single-stage reducers, but in the field of electric commercial vehicles, especially passenger cars, most of them are still manual gearboxes or with synchronizers and clutches.

Problems solved by technology

In the field of electric passenger vehicles, in order to give full play to the high-speed performance of the motor, most currently use single-stage reducers, but in the field of electric commercial vehicles, especially passenger cars, most of them are still manual gearboxes or with synchronizers and clutches. AMT gearbox, poor driving comfort

[0003] At present, most passenger cars use a single-machine deceleration system to make full use of the high-speed performance of the motor, which not only reduces the cost, but also improves reliability. Single-stage deceleration is very difficult, and the cost of the motor and reducer will increase a lot. Even the layout will be very difficult due to the increase in the power of the motor. It will cause efficiency loss. Even if there is an automatic transmission AMT scheme, it is a scheme with a clutch and a synchronizer, or with a selection and shifting mechanism. The structure is complex and the cost is high.
