Problems solved by technology

[0002] With the development of the automobile industry, a large number of people will join the ranks of drivers through the driving school study test every year, so the demand for driving school coach cars is very high, and because the coach cars are usually used for low-speed vehicles such as facilities in the driving range most of the time For driving projects, the engine is running in an idling condition or at a low speed with low efficiency, which will not only cause more fuel consumption of the vehicle, but also emit more harmful substances. The driving school site is often small, but the vehicles and The trainees are concentrated, the harmful substances emitted by these exhaust gases are very harmful to personnel
[0003] Electric vehicles are favored by more and more people because they do not consume fuel and have no exhaust emissions, especially in places with high population density, such as driving schools, etc. Electric vehicles are undoubtedly very suitable, not only avoiding the low-speed fuel consumption of the engine The utilization rate is low, and there is no pollution to personnel due to the absence of exhaust emissions. However, because the utilization rate of traditional fuel vehicles is still dominant, the driving school test is still based on fuel vehicles. The working principle and driving experience of electric vehicles and traditional fuel vehicles They are all different, which makes it impossible for electric vehicles to be used in driving school coaches.

Embodiment Construction

[0018] The concrete implementation method of the present invention is as follows:

[0019] figure 1 It is the rotational speed-torque running curve diagram of the electric coach vehicle using the braking method of the present invention. In order to show that the direction of the torque is opposite to the running direction of the vehicle, the direction of the torque axis in the figure is downward.

[0020] The braking method of the invention includes coasting braking and parking braking. According to the motor speed, it is mainly divided into three stages. stage, which is the idling stage; the speed greater than n1 is the third stage, which is the vehicle running stage.

[0021] Coasting braking in this embodiment is: when the vehicle is running, the gearbox is in neutral or the clutch is disengaged or there is an accelerator signal (that is, the accelerator pedal has a certain opening), no braking force is provided; When the gearbox is in the driving gear and the clutch is e...

Abstract

The invention discloses a braking method for an electric coach vehicle. A motor is utilized to simulate a braking mode of an engine, and the braking mode comprises a sliding brake and a parking brake. The driving feel of a driver is as same as or similar to the traditional fuel vehicle, and the adding of the parking brake power also can stop the vehicle sliding after the flameout of the vehicle, so that the happening of accidents, such as the vehicle being out of control, can be prevented. Meanwhile, the application of an electric vehicle to a coach vehicle can be promoted.

Description

technical field [0001] The invention relates to a coach car, in particular to a braking control method for an electric coach car. Background technique [0002] With the development of the automobile industry, a large number of people will join the ranks of drivers through the driving school study test every year, so the demand for driving school coach cars is very high, and because the coach cars are usually used for low-speed vehicles such as facilities in the driving range most of the time For driving projects, the engine is running in an idling condition or at a low speed with low efficiency, which will not only cause more fuel consumption of the vehicle, but also emit more harmful substances. The driving school site is often small, but the vehicles and The trainees concentrated on the fact that the harmful substances emitted by these exhaust gases are very harmful to personnel. [0003] Electric vehicles are favored by more and more people because they do not consume fu...
