    摘要: An obstacle avoidance control apparatus is provided with an obstacle detecting section, a first obstacle proximity distance prediction section, a second obstacle avoidance direction determining section, a target vehicle body slip angle setting section and a vehicle behavior controlling section. The obstacle detecting section detects preceding obstacles. The first obstacle proximity distance prediction section predicts a closest proximity distance between the host vehicle and a first (closest) obstacle. The second obstacle avoidance direction determining section determines a second obstacle avoidance direction to avoid the second obstacle. The target vehicle body slip angle setting section sets a target vehicle body slip angle, such that the host vehicle faces further inward of the turning direction as the proximity distance increases. The vehicle behavior controlling section controls the host vehicle so that an actual vehicle body slip angle coincides with the target vehicle body slip angle at the time of closest proximity.

    摘要: A tire state estimator includes a lateral force upper limit estimating section, a lateral force estimating section, and a tire slip angle estimating section. The lateral force upper limit estimating section calculates an estimated tire lateral force upper limit, on a basis of an estimated tire slip angle and a measured tire self aligning torque. The lateral force estimating section calculates an estimated tire lateral force, on a basis of the estimated tire lateral force upper limit calculated by the lateral force upper limit estimating section and the estimated tire slip angle. The tire slip angle estimating section calculates the estimated tire slip angle, on a basis of the estimated tire lateral force calculated by the lateral force estimating section and a measured vehicle state.

    摘要: A method and apparatus for rapidly causing a slip of a driving wheel to converge regardless of the change in vehicle conditions when the driving wheel is in a slip state. When a slip occurs on a driving wheel, a second driving force command value is calculated from a driving force control value controlled by driving force control means and an angular acceleration. The second driving force command value is calculated so that torque capable of being transmitted to a road surface by the driving wheel takes the maximum value. Therefore, even if the friction coefficient of road surface or the wheel load changes, the driving torque of driving wheel can be commanded properly, so that the slip can be converged rapidly. The occurrence of slip at the time of re-acceleration after slip convergence can be avoided.

    摘要: This invention relates to a valve timing control device for a vehicle engine (2) which performs combustion stop in a predetermined vehicle running condition. The predetermined vehicle running condition comprises, for example, engine startup, and combustion stop is performed by stopping fuel supply to the engine (2) or stopping ignition of the supplied fuel. The device comprises an actuator (51A, 52, 55, 61) which varies the timing of an intake valve of the engine (2) according to an input signal, and a microprocessor (16, 31) which outputs the signal to the actuator (51A, 52, 55, 61). The microprocessor (16, 31) is programmed to determine whether or not combustion has stopped (S80), and when combustion has stopped, control the signal so that the open/close timing of the intake valve is retarded compared to the case when combustion has not stopped (S94).

    摘要: An obstacle avoidance path computing apparatus is provided with a preceding object detecting section, a host vehicle information detecting section, a preceding object arrival region estimating section and a preceding object avoidance path setting section. The preceding object detecting section detects a preceding object. The host vehicle information detecting section detects host vehicle information. The preceding object arrival region estimating section calculates an estimated arrival region within which the preceding object could arrive after a prescribed amount of time has elapsed since the preceding object was detected, based on an estimated attribute of the preceding object from the preceding object information. The preceding object avoidance path setting section calculates an avoidance path that will not encroach on the estimated arrival region based the preceding object information and the host vehicle information.
