Title:
A control device for vehicles
Document Type and Number:
Japanese Patent JP6272203
Kind Code:
B2
Abstract:
The embodiment provides a vehicle control unit including a road surface friction coefficient estimation module. The road surface friction coefficient estimation module estimates a road surface friction coefficient based on a parameter other than a body speed. The vehicle control unit further includes first and second torque increment setting modules. The first second torque increment setting module sets an initial value of a torque increment to be used in the torque control when a start thereof is detected. The initial value of the torque increment is set based on the road surface friction coefficient. The second torque increment setting module sets a current value of the torque increment after the initial value has been set. The current value of the torque increment is set based on the previous value thereof and a change in the slip amount.
