    Abstract: A vehicle is equipped with a motor that receives a supply of electric power, which is output from a battery and is boosted up by a DC/DC converter circuit, via an inverter circuit and outputs a torque to a drive shaft. In response to an estimated variation in road surface condition based on a decrease in angular acceleration of the drive shaft to be less than a threshold value ref during a slip, the control procedure of the invention adds a predetermined value to a torque upper limit Tmax, which is set at the time of the occurrence of the slip, and thereby updates the torque upper limit Tmax to start cancellation of torque restriction. The control procedure then updates the torque upper limit Tmax by a slope of a small time change to restrain the degree of cancellation of the torque restriction.

    Abstract: A data generating system and a method to be used in a host vehicle for generating distance data as to the distance between the host vehicle and a target object travelling in the predicted path of the host vehicle and velocity data as to the velocity of the target object. When a target object is detected, the distance data is set to correspond to a measured distance value, the velocity data is set to correspond to a value determined based on a measured value of the relative velocity of the target object and the velocity of the host vehicle, and these data are stored in a memory. When the target object ceases to be detectable at the same time as the host vehicle is travelling in a curve, a value of the distance between the host vehicle and the target object is repeatedly estimated based on the latest distance and velocity data stored in the memory and the velocity of the host vehicle, whereupon the distance data is set to correspond to the estimated value and stored in the memory.

    Abstract: An acceleration control system controls acceleration of a vehicle to match the driver's feeling. In this control, the vehicle is controlled so that acceleration remains constant at the initial stage and then a differentiated value of a square power of a vehicle speed remains constant. This control is based on the finding of a normal acceleration operation attained by a driver. A linear relation exists between the acceleration in the initial stage of acceleration and the differentiated value of the square power of the speed. Switching of control from the constant acceleration to the constant differentiated value of the square power of the speed is made at a change-over speed determined by the linear relation.

The operation of the engine is controlled with the greater between the target throttle opening THtag and a required throttle opening THreq corresponding to an accelerator opening Acc (step S290).

  • Patent number: 7392120
    Abstract: In a vehicle dynamics control apparatus capable of balancing a vehicle dynamics stability control system and a lane deviation prevention control system, a cooperative control section is provided to make a cooperative control between lane deviation prevention control (LDP) and vehicle dynamics stability control (VDC). When a direction of yawing motion created by LDP control is opposite to a direction of yawing motion created by VDC control, the cooperative control section puts a higher priority on VDC control rather than LDP control. Conversely when the direction of yawing motion created by LDP control is identical to the direction of yawing motion created by VDC control, a higher one of the LDP desired yaw moment and the VDC desired yaw moment is selected as a final desired yaw moment, to prevent over-control, while keeping the effects obtained by both of VDC control and LDP control.

  • Patent number: 7367414
    Abstract: In a constant speed drive (in an auto cruise), the procedure of the invention executes proportional control to set an accelerator opening Acc corresponding to an observed vehicle speed and a target vehicle speed. When the accelerator opening Acc is less than a preset opening A2 included in a dead zone where a torque demand Tr* is kept equal to 0, the procedure corrects the accelerator opening Acc to have a corresponding torque demand Tr* included in a negative zone where the torque demand Tr* takes negative values and linearly increases. This arrangement heightens the linearity of the graph of the torque demand Tr* against the accelerator opening Acc in the constant speed drive, compared with the linearity in a standard drive.

    Abstract: A cruise control for a vehicle that detects an inter-vehicle distance to a preceding vehicle. A first vehicle speed instruction value is computed based one the inter-vehicle distance. Curve information of a curve in the road ahead of the vehicle is detected, and a second vehicle speed instruction value is computed for traveling on the curve based on the curve information. A final target vehicle speed is set based on the vehicle speed instruction values. When the vehicle travels through the curve while the first vehicle speed instruction value is larger than the second vehicle speed instruction value, the final target vehicle speed is set to a vehicle speed higher than the second vehicle speed instruction value and lower than the first vehicle speed instruction value. The speed of the vehicle is controlled based on the final target vehicle speed.

  • Patent number: 7308961
    Abstract: A maximum permissible acceleration is calculated so as to take into account vehicle stability, driver's comfort, road surface information and traffic information, driver's specific taste in acceleration and deceleration, and the like. An acceleration limiting process is carried out, in which a feedback gain in vehicle speed feedback control is corrected as may be necessary based on a relationship between the maximum permissible acceleration and actual acceleration information so as to keep the actual acceleration within the maximum permissible acceleration. The present invention thereby makes it possible to control a vehicle speed within a desired acceleration range even under conditions, in which there is a large vehicle speed deviation as in a resume mode, causing an excessively large acceleration or deceleration to tend to occur. Auto cruise control offering an outstanding safety and comfort can thus be implemented.
