[0034] Hybrid commercial vehicle braking mode management method. This method is based on EBS2 to achieve braking energy management. Under the premise of not changing the original EBS2 control mode, the hybrid motor is incorporated into the original EBS2 controlled braking element, and in the braking process In the medium, hybrid motor braking is preferred, that is, when the power of the hybrid motor can meet the braking power required by the vehicle, only the hybrid motor braking takes effect; and when the...

The invention relates to a hybrid commercial vehicle braking mode management method. The method comprises the steps: monitoring and collecting brake pedal signals continuously; judging whether a vehicle is in a deceleration braking state; if the vehicle is in the deceleration braking state, calculating the required braking torque; calculating the maximum braking torque which can be provided by thehybrid motor at the current moment; if the maximum braking torque is equal to 0, determining that the brake mode is mechanical braking and auxiliary braking; if the maximum braking torque is smallerthan the required braking torque, judging that the braking mode is regenerative braking, mechanical braking and auxiliary braking of the hybrid motor; otherwise, collecting the vehicle speed at the current moment; calculating the rotating speed of the hybrid motor; if the rotating speed of the hybrid motor is not less than the minimum starting rotating speed of the hybrid motor, judging that the braking mode is regenerated braking of the hybrid motor; otherwise, determining that the braking mode is mechanical braking. According to the invention, the hybrid power motor is introduced into the braking system, so that the braking energy recovery and management of the hybrid power commercial vehicle based on the EBS are realized.
Description
Technical field [0001] The invention relates to the technical field of hybrid vehicle braking energy management, and in particular to a method for managing the braking mode of a hybrid commercial vehicle. Background technique [0002] The existing EBS (Electronic Brake Systems) is an upgrade of ABS (antilock brake system) in the control mode and function. The EBS controller controls the intelligent braking components on the whole vehicle and performs the braking principles under different braking requirements. The braking energy is distributed to control the braking process of the whole vehicle, and achieve the purpose of safe braking such as anti-locking, anti-skidding, and transition from low road to high road. [0003] At present, EBS includes four types of brake components: mechanical brake, retarder, exhaust brake, and engine brake. These four types of brake components can only achieve braking energy management for fuel vehicles. [0004] The disadvantage of the prior art is th...
