    摘要: An attitude angle estimating means computes a derivative amount of an attitude angle with respect to a vertical axis of a vehicle body, and integrates the computed derivative amount of the attitude angle, and estimates the attitude angle. On the basis of the sensor signal and the attitude angle estimated by the attitude angle estimating means, a computing means computes a derivative amount of the attitude angle obtained from equations of motion for vehicle motion. A drift amount estimating means estimates a sensor drift amount of the sensor signal by using a relationship that, when taking a sensor drift amount of the sensor signal into consideration, the derivative amount of the attitude angle computed by the attitude angle estimating means, and a value that considers a sensor drift amount in the derivative amount of the attitude angle computed by the computing means, are equal.

    摘要: Various state amounts of a vehicle body detected by various types of sensors are captured (step 102). A maximum frictional force Fimax is calculated for each of wheels (steps 104 to 110). By use of the maximum frictional force Fimax and other physical quantities, a performance function not dependent on respective magnitudes of a vehicle body generating force and a yaw moment is defined, which performance function is prepared by means of a performance function in a case in which the vehicle body generating force is larger than the yaw moment, and a performance function in a case in which the vehicle body generating force is not larger than the yaw moment (step 112). A resultant force qi of tire generating forces acting on respective wheels is calculated by means of a third performance function (step 114), and braking and driving forces of each wheel, and a steering angle of each wheel are obtained by means of the calculated direction in which the resultant force of tire generating forces acts on the wheels (step 116). Based on the obtained braking and driving forces and steering wheel of each of the wheels, these wheels are each controlled (step 118).

    摘要: The invention provides a vehicle motion control device capable of realizing optimum avoidance control in the case of an emergency. The vehicle motion control device includes an external environment detection unit for detecting external environment, and a travel state detection unit for detecting a travel state of a driver's vehicle. An obstruction is detected based on the external environment detected by the external environment detection unit, and an environment map indicating obstructions is created. A control device estimates a plurality of possible avoidance actions for avoiding an obstruction based on the environment map and the travel state of the driver's vehicle detected by the travel state detection unit. The control device estimates collision damage according to each avoidance action estimated by the avoidance action estimation unit, and selects an appropriate avoidance action based on the estimated collision damage. The control device controls a vehicle such that the selected avoidance action is carried out.

    摘要: In a steering apparatus, in accordance with a grip limit control process (30b′), it is determined whether or not a grip degree ε estimated by a grip degree estimation arithmetically operating process (30a) is less than a predetermined grip degree (ε′), and in the case that it is determined that an estimated grip degree (ε) is less than the predetermined grip degree (ε′), the process applies such a feeling that a steering operation by a steering wheel suddenly becomes light to a driver, by suddenly increasing an assist quantity by a motor (M), thereby notifying the driver of the matter that the grip degree of a steered wheel is close to a limit. Therefore, it is possible to transmit to the driver a probability that a side slip is generated by further turning the steering wheel 21 in the same direction as the current direction, thereby calling the driver's attention for steering. Accordingly, there is an effect that a stability of a vehicle behavior can be improved without applying any fear of insecurity to the driver.

    摘要: In accordance with a vehicle motion control apparatus, a steering wheel torque (Th) generated in accordance with an operation of a steering wheel is determined in accordance with a steering wheel torque arithmetic process (30b) by EPS_ECU by using a steering torque (Tp) generated in a second steering shaft of a gear ratio variable mechanism, a motor torque (Tvm) generated by a motor (32m) of the gear ratio variable mechanism and a rotation angle (θvm) of the motor (32m), on the basis of a dynamic equation expressing a torque transfer by the gear ratio variable mechanic Accordingly, even in the case that the vehicle motion control apparatus employs a structure that the gear ratio variable mechanism is interposed between the steering wheel and a torque sensor, the steering wheel torque (Th) can be known without adding any new torque sensor or the like. Therefore, it is possible to improve a motion controllability of the vehicle without increasing a number of parts by using the steering wheel torque (Th) for an ESP control process (30a).
