PURPOSE:To make a car stoppable so smoothly, by selecting a threshold value of car speed variations with a car speed, in case of a car braking device. CONSTITUTION:When an accelerator is released free and a switch 53 is pushed, a signal is fed to a controller 52. If car speed variations are within the setting range, each of solenoid valves 51a and 51b is turned on or off whereby braking force is kept up. And, in advance of this, clearing of detection time for car speed variation, setting of initial speed and braking force retention are all displayed. When the car speed variation exceeds the specified range, these solenoid valves 51a and 51b are turned off together, reducing the braking force. Likewise, prior to this, clearing of detection time for car speed variation, setting of the initial speed and braking force reduction are all displayed. When the existing car speed becomes below the preset car speed, alteration of the threshold value takes place, thus a small value is set. |
