Vehicle braking-force control device

摘要

A braking-force control device has a brake control function for performing brake control on a front outside wheel when a vehicle is detected to be in an oversteer condition during a turning operation and for performing brake control on a rear inside wheel when the vehicle is detected to be in an understeer condition during a turning operation. For preventing the oversteer condition, a command for reducing the engine torque is output. On the other hand, for preventing the understeer condition, the engine torque is limited in accordance with a permissible engine torque value that is calculated on the basis of a road-surface friction coefficient, and ground loads and lateral tire forces of individual wheels. If it is detected that engine braking is in operation, the engine torque is adjusted to substantially zero.
