Whether running status meets energy regenerating condition.
Wherein, above-mentioned steps 201- steps 202 implement process and principle, are referred to step in above-described embodiment
101 specific descriptions, here is omitted.
Step 203, if meeting, according to the current opening value of brake pedal, auxiliary brake torque value is determined.
It is understood that when driver will carry out different degrees of control for brake to electric automobile, power that can be different
Brake pedal is acted on, so that different degrees of change occurs for the position of brake pedal.Angular transducer or displacement transducer
Corresponding electric signal can be exported, so that at Brake energy recovery according to the angle or change in displacement of the brake pedal detected
Output valve of the device according to sensor is managed, the opening value of brake pedal is determined, and then determine auxiliary brake torque value.
Specifically, the opening value of brake pedal can be pre-set, the mapping relations with auxiliary brake torque value, so that
Determine after the current opening value of brake pedal, auxiliary brake torque value can be determined according to default mapping relations.
In addition, auxiliary brake torque value is bigger, Brake energy recovery intensity is bigger.
For example, Brake energy recovery intensity can be divided into 3 grades in advance, and pre-sets brake pedal aperture
More than first threshold, less than brake pedal maximum opening 15% when, Brake energy recovery intensity is most weak, auxiliary brake torque value
For 30 Newton meters (Nm)；When brake pedal aperture is between the 15% of brake pedal maximum opening and 50%, braking energy
Recovery intensity is moderate strength, and auxiliary brake torque value is 50Nm；Brake pedal aperture is in brake pedal maximum opening
When between 50% and 100%, Brake energy recovery maximum intensity, auxiliary brake torque value is 70Nm.If then according to being fixed on
The output valve of sensor on brake pedal, the aperture for determining brake pedal is the 10% of brake pedal maximum opening, then can be with
It is 30Nm to determine auxiliary brake torque value, so as to 30Nm auxiliary brake torque value, carry out Brake energy recovery processing.
If it should be noted that when carrying out Brake energy recovery processing, the aperture of brake pedal changes, then can be right
Auxiliary brake torque value is adjusted, and to adjust the intensity of Brake energy recovery, improves the efficiency of Brake energy recovery.
Such as, it is assumed that the aperture of current brake pedal is the 10% of brake pedal maximum opening, auxiliary brake torque value is
30Nm, if Brake energy recovery processing unit, determines that the aperture of brake pedal is changed into the 20% of brake pedal maximum opening, then
The methods such as operating current that can be by adjusting generator, the 20% of brake pedal maximum opening is adjusted to by auxiliary brake torque
Corresponding auxiliary brake torque value 50Nm.
The Brake energy recovery processing method that the embodiment of the present application is provided, first according to the null of electric vehicle brake pedal
Journey cut off, determines first threshold, then when it is determined that the aperture of electric vehicle brake pedal is more than first threshold, judges electronic
Whether the current running status of automobile meets energy regenerating condition, if meeting, according to the current opening value of brake pedal, it is determined that
Auxiliary brake torque value.Thus, by being more than first threshold in the aperture of electric vehicle brake pedal, and electric automobile is current
When running status meets energy regenerating condition, start Brake energy recovery processing, and according to the aperture of brake pedal, to Brake Energy
The strength grade that amount is reclaimed is configured, it is to avoid the error starting of braking energy recovering function, reduces Brake energy recovery work(
