I.e. according to engine speed, GES, ignition signal (ignition key position), accelerator pedal signal, brake pedal signal
With the running status of the comprehensive descision vehicle such as acceleration signal.For example when gear be non-D, R gear, speed for 0 can determine that for
Vehicle is dead ship condition；When vehicle is not that 0, gear is kept off for non-D, R, speed is 0 in fired state, engine speed
Then can determine whether as driver's temporary parking or wait red light phase.
S3：If travel condition of vehicle is dead ship condition, controls electronic parking actuator and provide brake force to keep for vehicle
Stationary vehicle.
In one embodiment of the invention, with reference to shown in Fig. 3, step S3 namely static state clamp parking control model, tool
Body includes：For example by the angle of gradient of obliquity sensor real-time detection vehicle parking position；If the angle of gradient of vehicle parking position

(for example, maximum braking force) is keeping stationary vehicle；If the angle of gradient of vehicle parking position is less than or equal to predetermined angular,
For example when vehicle is on level road or the less road of the gradient, then controls electronic parking actuator and apply the second caste system power to wheel
To keep stationary vehicle, wherein, the first estate brake force is more than the second caste system power.Wherein, why brake force is divided into
The first estate brake force and the second caste system power are distinguished, is for the service life for extending electronic parking actuator.

In kinestate, dynamic instrumentation power here can make car two produce actuate in short-term but it is unlikely cause larger deceleration, therefore pass through
Monitoring acceleration sensor signal change amplitude A is constant, is judged to that vehicle static stops, and electronic parking control unit then applies car
Parking clamping force (the first estate brake force).If acceleration transducer change in value exceed predetermined threshold value, can determine that for
Vehicle-state is dynamic brake hard, and now electronic parking control unit still cannot judge concrete speed size, ring for safety
P is answered to keep off the demand of parking, electronic parking control unit applies a certain constant safe clamping force calibration value F2 (the second brake force),
Here safe clamping force calibration value F2 is able to maintain that vehicle keeps soft deceleration, similar to the clamping for dubbing braking effect
Power.In this moderating process, whether the numerical value of monitoring acceleration sensor has the change behavior B for returning to certain constant value all the time,
If it is, judging that vehicle reaches static dead ship condition and applies completely parking clamping force F3 (the 3rd brake force) to wheel then.
If gear level is pushed D gears by driver before vehicle stopped state confirms, electronic parking control unit carries out release operation simultaneously
Clamping pattern is exited, to ensure the traveling demand of driver.
To sum up, the method for the above embodiment of the present invention eliminates automatic transmission parking gear (P gears) relevant latch actuator,
Replace and parking power is applied to wheel using electronic parking, avoid because of vehicle improper movement after a stoppage (such as road surface not
Flat, ramp car slipping etc.) and the reverse power transmission impairment automatic transmission associated mechanical parts of wheel to variator are caused, together
When reduce integral vehicle cost, improve the integrated level of vehicle resources.
