Title:
BRAKING DISTANCE SUPPRESSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/013376
Kind Code:
A1
Abstract:
A braking distance suppression device used in an electrically driven working vehicle is equipped with a safe vehicle speed calculation unit (9) for calculating, based on slope information, loading capacity information, road surface friction information, vehicle speed information, and the braking torque characteristics of an electric motor, a safe vehicle speed at which the braking distance by an electric braking device becomes less than or equal to a threshold value. Preferably, the braking distance suppression device is equipped with: a deceleration limit vehicle speed calculation unit (5) for calculating a deceleration limit vehicle speed at which the deceleration by the electric braking device becomes less than or equal to a threshold value; a vehicle speed determination unit (8) for determining from the results of comparing the vehicle speed information with the safe vehicle speed and the deceleration limit vehicle speed whether the vehicle can stop by the electric braking device within a set distance; a notification instruction unit (17) for warning the operator or prompting the operator to perform a braking operation according to the determination results; an operation determination unit (14) for determining a notification setting from a pedal operation amount; and a logical product calculation unit (15) for outputting a notification operation setting on the basis of the determination results of the vehicle speed determination unit (8) and the operation determination unit (14).
