PROBLEM TO BE SOLVED: To provide a driving force control system of a mechanical throttle vehicle capable of achieving practical responsiveness in spite of its low cost.SOLUTION: In a vehicle (1) mounted with an engine (2) having a mechanical throttle valve, a brake (31) is pressurized to control driving force when a slip ratio of a driving wheel (3) exceeds a threshold, and while the slip ratio is exceeding the threshold, delay angle control of the engine is performed while maintaining the brake in a pressurized state (P1). When an engine control prohibition signal is transmitted in the meanwhile, the driving force is controlled, bringing the brake into a second pressurized state (P2) which is higher than the above pressurized state (or a first pressurized state P1).
【課題】低コストでありながらも実用的な応答性を達成できる機械式スロットル車両の駆動力制御システムを提供する。【解決手段】機械式スロットル弁を備えたエンジン(2)を搭載した車両(1)において、駆動輪(3)のスリップ率が閾値を超えた場合にブレーキ(31)を加圧して駆動力を制御し、前記スリップ率が前記閾値を超えている間は、前記ブレーキを加圧状態(P1)に維持しながら前記エンジンの遅角制御を行う。その間にエンジン制御禁止信号が発信された場合には、前記ブレーキを前記加圧状態(第1の加圧状態、P1)よりも高い第2の加圧状態(P2)として駆動力を制御する。【選択図】図2
