An electric vehicle control system

Abstract

The invention discloses an electric car control system. The electric car control system comprises an ECU, a braking assembly, a power assembly, a headlamp assembly, a night detecting assembly and a motor. The braking assembly comprises a braking master pump, a rear wheel drum braking unit, a front wheel disc braking unit, a braking pedal, a braking pedal sensor and a vacuum auxiliary braking unit.The headlamp assembly comprises a dipped headlamp, a relay I, a high-beam lamp and a relay II, and a power unit supplies power to the dipped headlamp through the relay I and supplies power to the high-beam lamp through the relay II. The relay I and the relay II are connected with the ECU. The ECU sends a corresponding control instruction to the headlamp assembly according to a detecting signal ofthe night detecting assembly. According to the electric car control system, low beams and high beams can be automatically switched, braking can be accurately carried out, and the cruising ability ofa battery can be improved.

Description

technical field [0001] The invention belongs to the technical field of new energy electric vehicles, and in particular relates to an electric vehicle control system. Background technique [0002] With the needs of social development, new energy is getting more and more attention, and the corresponding demand for new energy electric vehicles will also be higher and higher. The shortcomings of new energy electric vehicles are as follows: [0003] 1. Endurance. The battery is related to the endurance. The current capacity of each battery is fixed and unchangeable, and the heat dissipation efficiency of the battery is low, causing its own temperature to be too high. This is a safety hazard for electric vehicles. [0004] 2. The brake system of electric vehicles is still unable to make quick judgments on the normal braking and emergency braking of electric vehicles and adopt corresponding correct measures to achieve a faster braking effect. Moreover, in the process of use, accide...

AI Technical Summary

Problems solved by technology

[0003] 1. Endurance. The battery is related to the endurance. The current capacity of each battery is fixed and unchangeable, and the heat dissipation efficiency of the battery is low, causing its own temperature to be too high. This is a safety hazard for electric vehicles.

[0004] 2. The brake system of electric vehicles is still unable to make quick judgments on the normal braking and emergency braking of electric vehicles and adopt corresponding correct measures to achieve a faster braking effect. Moreover, in the process of use, accidents caused by accelerator pedal braking There are also many, and the existing electric vehicles cannot take effective preventive measures for this kind of misoperation

[0005] Moreover, no matter electric vehicles or ordinary fuel-efficient vehicles, they all have a bad habit of using the high beams at night, but when they meet with the opposite vehicle, the driver does not actively switch the high and low beams, and the high beams directly shine on the car. Oncoming vehicles cause strong light interference to oncoming drivers and are prone to malfunctions
