<P>PROBLEM TO BE SOLVED: To smoothly start on an ascending sloped road, and to cope with the situation where smooth starting cannot be made. <P>SOLUTION: Braking for front wheels output with power from an engine is released, under conditions where braking for rear wheels is held (S140), and a throttle opening TH is made large gradually, to bring an engine speed into a target speed Ne* corresponding to a road face slope θ(S180), when a driver returns a brake pedal on an up-hill sloped road. Braking for the rear wheels is released (S240), when an output torque Tem output to the front wheels and the rear wheels gets larger than a target torque Td*, corresponding to the road face slope θ, to start. The start is smoothed thereby on the ascending sloped road. The braking for the front wheels is returned to an original state to inhibit ascending sloped road start control (S260, S270), when the slippage of the front wheels is determined before the output torque Tem comes to the target torque Td*, and a stoppage condition is held, so as to cope with even the situation that does not allow smooth start. <P>COPYRIGHT: (C)2007,JPO&INPIT |
