Japanese Patent JP2018086927
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To determine whether or not the braking force of a brake on the side of a trailer towed by a tractor has been reduced.SOLUTION: A braking force reduction determination apparatus 10 is installed in a tractor 2 of a combination vehicle 1 equipped with an EBS6. A CPU of the braking force reduction determination apparatus 10 functions as a vehicle body speed estimating part 17, a slip ratio calculating part 18, a low slip ratio state determination part 19, and an alarm determination part 22. The vehicle body speed estimating part 17 estimates the tractor 2 vehicle body speed. The slip ratio calculating part 18 calculates a tractor side slip ratio and a trailer side slip ratio. The low slip ratio state determination part 19 determines whether or not wheels on a trailer 3 side have entered a low slip ratio state on the basis of the trailer side slip ratio and the tractor side slip ratio. The alarm determination part 22 determines whether or not the braking force of a brake 8 on the trailer 3 side has been reduced on the basis of the determination results of the low slip ratio state determination part 19.SELECTED DRAWING: Figure 2
