BRAKE CONTROL DEVICE FOR EXECUTING ADDITION CONTROL BY USE OF SPEED CALCULATION

摘要

PROBLEM TO BE SOLVED: To improve an accuracy of brake control.SOLUTION: A command value calculation part 11 calculates a brake force command value from a brake command and a weight of a vehicle. A pattern calculation part 13 calculates a target speed from a command deceleration and a vehicle speed at a start time within a period determined from the time when a change of the brake command is detected. An addition control instruction part 14 compares the vehicle speed at a determined timing and the target speed with each other, and when the vehicle speed is higher than the target speed, instructs start of an addition control to a control part 12. The control part 12 sends a brake force command value received from the command value calculation part 11 to a mechanical brake when start of an addition control is not instructed by the addition control instruction part 14, and sends the brake force command value to which a determined command value is added to the mechanical brake when start of an addition control is instructed by the addition control instruction part 14.SELECTED DRAWING: Figure 1
