Problems solved by technology
[0002] In the prior art, hybrid vehicles usually use a dedicated hybrid gearbox, so that when braking, the hybrid vehicle generally uses the drive motor to generate electricity for energy recovery and braking. However, when the battery pack of the hybrid vehicle has a high power and When the battery pack can no longer be charged, the brake calipers can only be used to generate braking. During the long-term braking process of the brake calipers, it will inevitably cause heat and wear, and the brake friction pads may be burned on long downhill slopes. danger

Embodiment
[0033] Please refer to figure 1 , an embodiment of the present application provides a braking control method for a hybrid vehicle, the method comprising:
[0034] S101. When it is detected that the current driving condition of the hybrid vehicle is a long downhill condition, acquire the recovered energy that the hybrid vehicle can recover under the long downhill condition, and acquire the The stored energy that can be stored in the battery pack of a hybrid vehicle;
[0035] S102. When the recovered energy is greater than the stored energy, determine an additional power consumption strategy according to the recovered energy and the stored energy;
[0036] S103. When the hybrid vehicle is in the long downhill working condition, execute the extra power consumption strategy so that the actual recovered energy of the hybrid vehicle in the long downhill working condition is not greater than the store energy.
[0037] In the embodiments of this specification, a hybrid vehicle refe...

The invention discloses a braking control method of a hybrid vehicle. When it is detected that the current driving condition of the hybrid vehicle is a long downhill condition, the vehicle is acquired when the hybrid vehicle is in the long downhill condition. The recovery energy that can be recovered under certain conditions, and the storage energy that can be stored by the battery pack of the hybrid vehicle; when the recovery energy is greater than the storage energy, according to the recovery energy and the storage energy, determine additional Power consumption strategy; when the hybrid vehicle is in the long downhill condition, execute the extra power consumption strategy so that the actual recovered energy of the hybrid vehicle in the long downhill condition is not greater than The stored energy. The invention discloses a braking control method and device for a hybrid vehicle, and the hybrid vehicle, which can effectively reduce the probability of brake friction pads being burned out under long downhill conditions.
