Vehicle having slip suppressing device and suspension control device

A vehicle which comprises:

• a vehicle body;
• a power unit mounted in said vehicle body;
• at least a pair of driving wheels rotated by an output from said power unit;
• suspension devices between said driving wheels and said vehicle body for adjusting the height of said vehicle body relative to said driving wheels;
• suspension control means for controlling a suspension state of said suspension devices;
• slip detection means for detecting a slip state of said driving wheels;
• and
• slip suppressing means for, when said slip detection means detects a slip of said driving wheels, decreasing a rotating force of said drive wheels to suppress a slip, and for outputting a control signal to said suspension control means to increase the height of said vehicle body relative to said driving wheels.

A vehicle which comprises:

• a power unit;
• at least a pair of driving wheels rotated by an output from said power unit;
• vehicle body height detection means for detecting a height of a vehicle body relative to said driving wheels where said driving wheels are arranged;
• fluid pressure cylinders inserted between said vehicle body and said driving wheels for adjusting the height of said vehicle body where said driving wheels are arranged;
• a fluid pressure source for supplying a high-pressure working fluid to said fluid pressure cylinders;
• flow control means for controlling supply and discharge of the high-pressure working fluid to and from said fluid pressure source to obtain a predetermined vehicle body height on the basis of the detected result from said vehicle height detection means;
• slip detection means for detection of a driving force slip of said driving wheels;
• brake control means for decreasing the rotating force of said driving wheels and for outputting a control signal on the detection of slip;
• slip suppressing means for operating, when said slip detection means detects a slip of said driving wheel, said brake means to suppress the slip;
• and
• suspension control means for receiving said control signal from said brake control means and controlling said flow control means to begin to increase the vehicle body height relative to said driving wheels before said slip suppressing operation is performed by said slip suppressing means.
