装置。 In an automobile equipped with an engine that has a fuel injection control means that can control the amount of fuel injection for each cylinder, there are sensors that detect the wheel speeds of driving wheels and non-driving wheels, and the driving wheels and non-driving wheels that are detected by both sensors. Drive wheel slip rate calculating means for calculating the slip rate of the drive wheels based on the speed of each wheel of the drive wheels, and engine control reduction amount determination for determining the necessary reduction amount of engine output according to the slip rate calculated by the calculation means. means and
When the amount of reduction determined by the engine control reduction amount determination means is less than the set amount, the amount of fuel injection to each cylinder is adjusted to correspond to the amount of reduction determined by the engine control reduction amount determination means. When the amount of decrease exceeds the set amount, the fuel injection control means is controlled to cut fuel injection to a specific cylinder and adjust the amount of fuel injected to the remaining cylinders to correspond to the amount of decrease. A traction control device for an automobile, comprising output torque control means.
