Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the anatomical connectivity schematic diagram of a kind of embodiment of the utility model.
Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, setting forth the utility model further below.
Braking of battery electric vehicle shown in Figure 1, slide, Stop Control System, the brake pedal 30, acceleration pedal 40 and the electric machine controller 20 that comprise motor 50, entire car controller 10 and be connected with entire car controller 10, electric machine controller 20 is connected with motor 50, entire car controller 10 in the present embodiment is connected by CAN a with electric machine controller 20, improves communication reliability.Car speed sensor 60 is connected with motor 50, in order to measure pure electric automobile driving process medium velocity.Force snesor 70 is in order to measure friction drag, aerobraking power suffered in pure electric automobile driving process.
Entire car controller 10 is also connected with a brake application curve generation module 80, and brake application curve generation module 80 is connected with car speed sensor 60 and force snesor 70 respectively.
Principle of work of the present utility model is as follows:
In vehicle sliding, brake process, car speed sensor 60 and force snesor 70 distinguish speed, suffered friction drag, aerobraking power in measuring vehicle driving process.According to the speed M curve of motor 50, calculate through brake application curve generation module 80, generate two regenerative braking M curves, send entire car controller 10 to, then control the working condition of motor by electric machine controller 20.Wherein two regenerative braking M curve states are as follows: 1. after accelerator releasing, provide a regenerative braking M curve again by moving to slide to brake process to motor, realize switching by moving to the undisturbed operating mode slided; 2. when stepping on brake pedal 30, according to the aperture of brake pedal 30, the braking force of mechanical-pneumatic, thering is provided a regenerative braking M curve to motor, by mechanical-pneumatic, motor regenerative braking combined action, realizing automobile from sliding to brake again to steady, the shockproof parking of stopping.
This system not only achieves the emergency brake braking function of conventional electric automobile, also the stationarity sliding, brake, stop in the normal driving process of electronlmobil is reached, achieve being recycled of the energy, improve the comfort level that passenger rides, without the need to increasing extra mechanical brake device, structure is simple.
More than show and describe groundwork of the present utility model and principal character and advantage of the present utility model.The technical personnel of the industry should be understood; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification sheets just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
