Description
Technical Field
The invention relates to the technical field of automobile part manufacturing, in particular to a brake system for a new energy automobile.
Background
At present, new energy vehicles generally have energy recovery designs. Due to the restriction of the braking regulations (such as GB 7258, GB 12676 and the like), most vehicle braking systems work synchronously when a driver presses a pedal, and a static friction material and a high-speed rotating friction material of a wheel are driven to rub with each other to generate braking force, so that the vehicle is forced to stop. During the period, a large amount of kinetic energy or potential energy of the vehicle is converted into useless heat energy, and is wasted; when descending a long slope, the heat energy can affect the thermal stability of the vehicle brake, and the brake is subjected to heat fading. The energy recovery design of the existing new energy vehicle is generally connected with a brake lamp switch, for example, a new energy vehicle air pressure braking energy feedback diaphragm type blocking control valve disclosed in Chinese patent literature, the publication number of which is "CN 108891399A", comprises a brake pedal brake valve, the brake pedal brake valve is connected with an air pressure brake pipeline, and the air pressure brake pipeline is connected with a service brake system to work; the brake pedal brake valve is also connected with a brake lamp switch and a brake analog quantity sensor; the brake lamp switch, the brake analog quantity sensor and the accelerator analog quantity sensor are connected to a vehicle control unit VCU, the vehicle control unit VCU conducts power generation slow braking to the motor through a motor control unit MCU, and energy is recovered to a power battery; a diaphragm type blocking control valve is arranged between the brake pedal brake valve and the air pressure brake pipeline, and meanwhile, the diaphragm type blocking control valve is also connected to a VCU (vehicle control unit). According to the structure, two identical blocking control valves are connected in series in two paths of air braking pipeline loops output by the automobile brake pedal brake valve, so that various control states are realized, and the air braking energy feedback of the whole automobile resource is integrated; however, when the brake lamp switch is used as a signal medium for signal transmission, because the brake lamp switches of new energy automobiles in the current market are different in types, the double-break condition can occur in part of the brake lamp switches, especially in the working process of the brake lamp switches of the double-circuit brake system, and the influence is little because the brake lamp switches of the traditional automobile pedal are only used for controlling the brake lamp switches. The new energy automobile needs to use a brake lamp switch signal for energy recovery, and when double break occurs, the signal input is abnormal, the system error report is caused, and the normal work of the energy recovery system is influenced.
Disclosure of Invention
Aiming at the problem that the brake signal transmission is abnormal due to the double-break condition in the process of carrying out signal transmission by using a traditional brake lamp switch as a signal medium in the prior art, the invention provides the brake system for the new energy vehicle.
In order to achieve the purpose, the invention adopts the following technical scheme:
the utility model provides an automobile-used braking system of new forms of energy, includes the braking assembly, the braking assembly includes brake pedal and connects in brake pedal's vacuum booster, vacuum booster includes interior air chamber and outer air chamber, interior air chamber and outer air chamber are separated through the baffle subassembly that sets up at vacuum booster middle part, be provided with the vacuum valve that is used for communicating interior air chamber and outer air chamber on the baffle subassembly, last being provided with of vacuum booster is used for connecting outer air chamber and external air valve, still be provided with the pressure sensor subassembly in the vacuum booster, the pressure sensor subassembly is connected in vehicle control unit. Vacuum booster still is the mainstream brake helping hand mode of new forms of energy car, carries out the evacuation through vacuum booster's electric vacuum pump to make the driver when trampling brake pedal, can be laborsaving. The pressure sensor assembly is arranged inside the vacuum booster, when the internal pressure of the vacuum booster changes, the pressure sensor can timely identify the pressure change and transmit the pressure signal to the vehicle control unit, so that the vehicle control unit can accurately identify the brake signal, the phenomenon that a brake lamp switch is interrupted due to the fact that the double-circuit signal is asynchronous when a double-circuit brake system brakes in the prior art is avoided, and the phenomenon is called double-break phenomenon. The double-break phenomenon may cause the abnormality of the braking signal, so that the judgment of the vehicle control unit is problematic, and the pressure sensor can perform 'insurance' on the braking lamp switch, ensure that the braking signal is timely and accurately transmitted to the vehicle control unit, and guarantee the cooperative work of other systems of the vehicle.

Preferably, the energy recovery system comprises a transmission and a flywheel, and the flywheel is connected with the automobile driving shaft through the transmission. The transmission device is used for being connected with a hydraulic pipeline of the braking system, the hydraulic pipeline pressurizes the brake when the automobile brakes so that the braking action is completed, the whole automobile brake determines whether to start the energy recovery system according to the state of the battery, when the energy recovery is needed, the flywheel runs and participates in the braking work, partial energy generated in the braking process is converted into mechanical energy of the motor running, and the motor becomes a power generation device and charges the battery.
Preferably, the braking system further comprises a brake lamp switch, the brake lamp switch is electrically connected with the energy recovery system, and the brake lamp switch is connected with a brake pedal. The stop lamp switch is used for lighting the stop lamp when the braking work is carried out, when the brake pedal is stepped on, the stop lamp switch is driven and works normally, the stop lamp switch is electrically connected with the energy recovery system, and the stop lamp switch can transmit the braking signal to the energy recovery system, so that the energy recovery system can still receive the braking signal under the condition of not depending on the pressure sensor.
Preferably, the brake assembly further comprises an alarm system connected with the vehicle control unit, the alarm system is electrically connected with the pressure sensor, and the alarm system is connected with the brake pedal. But pressure sensor's design real-time supervision vacuum booster's operating mode, break down when vacuum booster, especially common gas leakage phenomenon, whole car sensor can diagnose vacuum booster according to pressure sensor and brake light switch's working parameter, for example, not step on when the brake pedal, pressure sensor should read for zero this moment, and the brake light switch closes, if pressure sensor reading changes and changes even for atmospheric pressure, then show that vacuum booster appears gas leakage phenomenon, whole car controller restart alarm system this moment, suggestion driver's vehicle breaks down.
Preferably, the alarm system comprises a buzzer. The buzzer can continuously vibrate and timely remind a driver that the vacuum booster breaks down, and the vehicle controller returns to the forced start electronic parking system to maintain a normally open state during the continuous working period of the buzzer, so that potential safety hazards caused by the fact that the vehicle cannot continuously run are guaranteed.
