Title:
VEHICLE TRACTION CONTROL DEVICE
Document Type and Number:
Japanese Patent JP3473282
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To suppress hunting of engine output occured after controlling traction for preventing inertia slipping during up-shifting.
SOLUTION: When a decision part 21 decides that the condition of occurring inertia slip is completed before a clutch coupling degree measuring part 22 and a decision part 23 for deciding that clutching is completed, subsequent inertial slip at the instantaneous calculation time is estimated, and, the decision part 23 for deciding coupling degree and a calculation part 24 for subsequent inertial slip calculate the required brake liquid feed forward control value. Until a decision circuit 26 decides the finishing of inertial slip, the traction control value for throttle opening is maintained 27, and a throttle TCS valve maintaining part 27 stops the opening control of throttle for controlling traction, and a brake control part 28 calculates the feed-back control value of the brake liquid pressure, and adding the feed-forward control value of the brake liquid pressure to the feed-back value of the brake liquid pressure, the required brake liquid pressure is decided.
