Then, when the driving force from electromotor 3 being delivered to front-wheel (driving wheel) and make vehicle accelerate,
In the case of the value of above-mentioned difference in wheel speed Δ V becomes setting more than Δ V1 (Δ V Δ V1), it is judged that for front-wheel (driving wheel)
Slipping state.Be set forth in object lesson in this case, vehicle travel comprise non-freezing road surface and freeze road surface this
In the case of both roads, when the road surface that front-wheel is walked from freeze road surface be changed into non-freezing road surface time, the earth-grasping force of front-wheel
Being increased dramatically, average wheel speed Vf drops to close to the value of 0.Thus, the value of difference in wheel speed Δ V become setting Δ V1 with
On.
On the other hand, when the brake force of brake being applied to front-wheel (driving wheel) and make vehicle deceleration,
In the case of the value of above-mentioned difference in wheel speed Δ V becomes other setting below Δ V2 (Δ V Δ V2), it is judged that for front-wheel
The lockup state of (driving wheel).It is set forth in object lesson in this case, travels at vehicle and comprising non-freezing road surface and freezing
In the case of the road on knot both road surfaces, at the Braking of brake at the state (shape of brake pedal of front-wheel
State) under, it is changed into when freezing road surface from non-freezing road surface on the road surface that front-wheel is walked, the earth-grasping force of front-wheel drastically declines, braking
The brake force of device becomes the state exceeding the earth-grasping force from road surface.Now, 0 is become due to front-wheel average wheel speed Vf moment
Or be very close to 0 value, thus, the value of difference in wheel speed Δ V becomes setting below Δ V2.
Although additionally, here the situation (front-wheel is the situation of driving wheel) that vehicle is f-w-d vehicle being said
Bright, but, in the case of vehicle is rear wheel drive vehicle, trailing wheel is driving wheel, in the case of four-wheel drive vehicle, front and back
Wheel is driving wheel.
Additionally, Rule of judgment (the low-friction coefficient road that the road surface that vehicle is travelled is low-friction coefficient road (low μ road)
Judgement symbol Fa=0 → 1, road) carry out according to following (a)～(c).A () front-wheel skids.B () four wheels skid.(c) front wheel lock
Only.In the case of any one in these (a)～(c) lasting stipulated time (the 1st time) more than T1, it is judged that for vehicle row
Sail on low-friction coefficient road.Additionally, as an example, above-mentioned stipulated time (the 1st time) T1 can be: T1=
The 0.05(second).
On the other hand, the condition subsequent (low-friction coefficient road judgement symbol Fa=1 → 0) that low-friction coefficient road judges
Carry out according to following (d)～(f).D () front-wheel does not skid.E () four wheels do not skid.F () front-wheel does not has locking.At this
In the case of (d)～(f) equal duration T more than 2 and vehicle once stopped a bit, it is believed that vehicle the most no longer travels low
On coefficient of friction road, release low-friction coefficient road and judge.Additionally, as an example, above-mentioned time T2 is: T2=1.0
(second).
Fig. 4 is the table for ill-roaded Rule of judgment and condition subsequent are described.As shown in the table in fig. 4, bad road
The Rule of judgment (poor road judgement symbol Fb=0 → 1) on road is according to following (g), and (h) is carried out.That is, (g) and (h) two side are
In the case of establishment, it is judged that travel on poor road for vehicle.
G () can interpolate that and travel in ill-roaded state into vehicle.Specifically, vehicle speed sensor 73 detecting
Vehicle velocity V is (V1 V V2) in prescribed limit, and, accelerator open degree sensor 72 the accelerator open degree AP detected is regulation
