Abstract
A control method for a four-wheel drive vehicle includes the steps of detecting a braking operation, detecting an accelerator opening or throttle opening greater than or equal to a predetermined value, and regarding the operational condition of the vehicle as the absence of a braking signal in the case that the accelerator opening or throttle opening greater than the predetermined value is detected simultaneously with the detection of the braking operation.
Claims3
A control method for a four-wheel drive vehicle such that the control is changed in braking the vehicle, comprising the steps of:
- detecting a braking operation;
- detecting an accelerator opening or throttle opening greater than or equal to a predetermined value;
- and
- regarding the operational condition of said vehicle as the absence of a braking signal in case that said accelerator opening or throttle opening greater than or equal to said predetermined value is detected simultaneously with the detection of said braking operation.
A control method for a four-wheel drive vehicle having main drive wheels connected to a driving power source, auxiliary drive wheels adjustable in drive torque, and a speed increasing mechanism capable of being switched between a same speed condition and an increasing speed condition of said auxiliary drive wheels with respect to said main drive wheels, wherein said speed increasing mechanism can be switched to said increasing speed condition according to a running condition of said vehicle, said control method comprising the steps of:
- detecting a braking operation;
- detecting an accelerator opening or throttle opening greater than or equal to a predetermined value;
- and
- maintaining said speed increasing mechanism in said increasing speed condition in case that said accelerator opening or throttle opening greater than or equal to said predetermined value is detected simultaneously with the detection of said braking operation.
A control method for a four-wheel drive vehicle having main drive wheels connected to a driving power source, and auxiliary drive wheels, wherein the drive mode of said vehicle can be switched between a two-wheel drive mode and a four-wheel drive mode according to a running condition of said vehicle, said control method comprising the steps of:
- detecting a braking operation;
- automatically switching to said two-wheel drive mode when detecting said braking operation in said four-wheel drive mode;
- detecting an accelerator opening or throttle opening greater than or equal to a predetermined value;
- and
- maintaining said four-wheel drive mode in case that said accelerator opening or throttle opening greater than or equal to said predetermined value is detected simultaneously with the detection of said braking operation.
