A traction control device includes: rotation speed detectors (43FL to 43CR) provided to wheels; a control-start determiner (82) that determines whether or not to control a braking mechanism and a differential adjusting mechanism based on rotation speeds; a braking mechanism controller (84) that controls the braking mechanism based on a result of the determination of the control-start determiner (82); and a differential adjusting mechanism controller (85) that controls the differential adjusting mechanism based on the result of the determination of the braking-start determiner (82), in which the control-start determiner (82) includes: a right-left-wheel rotation speed difference calculating section (822); a front-rear-wheel rotation speed difference calculating section (823); and a control-start determining section (825) that determines whether or not to start controlling at least one of the braking mechanism and the differential adjusting mechanism when one of rotation speed differences reaches or exceeds a predetermined threshold.

A motor vehicle, particularly a military motor vehicle, comprising a vehicle chassis disposed on an at least two-axle suspension and further comprising an enclosed mission compartment accommodating the crew and disposed on the suspension, wherein at least two drive systems (4.1, 4.2) are provided, each having a combustion engine (6), particularly a diesel engine, of which a first front drive system (4.1) is disposed in the region of the front axle (2.1) and acts exclusively on the front axle (2.1), while a second rear drive system (4.2) is disposed in the region of a rear axle (2.2) and acts exclusively on at least one rear axle (2.2), wherein the two drive systems (4.1, 4.2) are connected to a common control system such that one drive system (4.1) can be operated as the master and the other drive system (4.2) as the slave.

The invention relates to a method for controlling the braking system (1) of a four-wheel drive motor vehicle. Said braking system comprises an electric regenerative brake, especially a generator (4), and a plurality of friction brakes (2), the entire braking torque being constituted of braking torque portions of the friction brakes (2) and the electric regenerative brake. The braking torque of the electric regenerative brake is shared out in defined proportions to the front and rear axle. The aim of the invention is to achieve an especially high stability of braking. For this purpose, the braking torque supplied by the electric regenerative brake is limited to such an extent that the wheel slip of one axle of the motor vehicle does not exceed a selectable maximum value.

In a vehicular braking control apparatus, a target regenerative braking force and a target factional braking force are calculated on the basis of a reference vehicle deceleration Gbt based on an amount of braking operation performed by a driver. Braking forces are usually controlled in a cooperative braking mode realized by regenerative braking and frictional braking (S100 to S210). Braking forces for wheels are controlled in a single braking mode realized by the frictional braking when a braking control is performed for the first time or for the last time in a predetermined number of times, and a correction coefficient (Kp) is calculated as a ratio of a reference vehicle deceleration (Gbt) to an actual vehicle deceleration (Gbx) during the braking control (S90, S220 to S280). The target frictional braking force is corrected by being multiplied by Kp (S190). Hence, a total braking force for the vehicle is prevented from fluctuating when the braking force control mode shifts between the cooperative braking mode and the single braking mode. Thus, the vehicle deceleration is prevented from abruptly changing (S110 to S210).

A hybrid vehicle is provided with means for setting a four-wheel drive condition which is a condition for switching from two-wheel drive to four-wheel drive, and an EV switch which, when turned on by an occupant of the vehicle, places the vehicle in an EV driving mode in which only an electric motor is used as the power source. The four-wheel drive condition setting means changes the four-wheel drive condition to reduce a region in which the vehicle operates in four-wheel drive when the EV switch is on as compared to when the EV switch is off. As a result, the vehicle operates in two-wheel drive more frequently, thus reducing power consumption.

The present invention relates to a vehicle driving system, wherein a differentiator (141, 142, 143) calculates the acceleration of the rear wheels. An acceleration threshold calculation means (144) enable the skid-detection acceleration threshold to be adjusted corresponding to the conditions of the vehicle. An acceleration skid-detection means (145) make a comparison between the acceleration of the wheels obtained by the differentiator (141, 142, 143) and the skid-detection acceleration threshold adjusted by the acceleration threshold calculation means (144), and determine whether or not a skid of the wheels has occurred, based upon the comparison result. Such an arrangement provides a vehicle driving force system having a function of detecting a skid even in a case that a skid of the wheels has occurred at a low acceleration of the vehicle.
