PURPOSE:To provide a speed change control device performing speed change control without worsening an antilock brake system (hereinafter called ABS) function, in a vehicle of automatic transmission (hereinafter called AT) provided with the ABS. CONSTITUTION:As a speed change line diagram, an ordinary speed change line diagram and automatic engine brake controlling speed change line diagram are left as built in an AT controller 14. When a signal of ABS actuated comes not from an ABS controller 15, the AT controller shifts a gear in accordance with the automatic engine brake controlling speed change line diagram. Accordingly, here is performed automatic engine brake control. However, when a signal of the ABS actuated comes, the AT controller shifts the gear in accordance with the ordinary speed change line diagram. Here since no automatic engine brake control is performed, an ABS function is also not worsened, and a large shock is also not generated in a vehicle. |
