Kilometer/hour), you can confirming the brake force deficiency of EPH causes this car that car slipping phenomenon, now controller meeting occurs
Sent to brake actuator and increase brake force instruction, brake actuator increases brake force to this car immediately, until this car speed is
Zero, untill vehicle stops completely, then persistently keep the indicating brake action, it is ensured that this car no longer slides or car slipping.
In view of in most instances, when vehicle temporary parking, (such as traffic light intersection temporary parking, waits for a green light, or gathers around
Stifled section is lined up stop-for-waiting), if driver's artificial long period lasting pin steps on brake pedal and takes this car braking to do manual work
(this car Brake lamp was persistently lighted more than 3 seconds), you can prove that driver also needs long period stop-for-waiting and is not intended to make
Control for brake is implemented to vehicle with this vehicle device tool parking brake or electronic brake system, now controller should export brake signal,
So that brake actuator performs braking workmanship operation to brake pedal, driver is to vehicle control with high safety for auxiliary.It is such
Advantage is that driver just immediately refuels again when car just stops in many cases, and (driver is to the artificial of brake pedal for starting
Braking workmanship was not over 3 seconds), now then intervened at once without parking braking servicing unit, otherwise can influence driver couple
Vehicle implements driveaway operation.Vehicle by stopping (vehicle speed pulse numerical value is 0 kilometer/hour) completely, and driver is not to vehicle
When taking oiling driveaway operation, vehicle speed pulse numerical value just can recognize that more than 0 kilometer/hour occurs car slipping phenomenon for this car, now
EPH can be intervened, and avoid continuing car slipping phenomenon.Only vehicle recognizes driver in complete halted state
Need persistently to implement brake pedal braking workmanship, or under the complete halted state of vehicle, driver is not taking vehicle
During oiling driveaway operation, vehicle speed number of pulses changes, in the case of recognizing vehicle generation car slipping phenomenon, parking auxiliary
The braking workmanship of device can intervene work.After EPH implements braking workmanship to this car, under any circumstance, only
This car gas pedal whereabouts is recognized, driver artificially implements driveaway operation to vehicle, or recognizes driver's manual control
On ＆ off switch on controller, when EPH is closed, the braking workmanship of EPH can release, and recover
To original state.When being able to ensure that parking braking servicing unit workmanship maloperation does not occur for aforesaid way, avoids influenceing driver
Normal operating is implemented to vehicle, so as to have influence on the normally travel of vehicle, or even new potential safety hazard is brought to driving, makes the dress
More intelligent, hommization is put, improves the user experience of driver.
