摘要:
An object of the vehicle body vibration-damping control device according to the present invention is to achieve a targeted effect for damping the vehicle body vibration regardless of the responsiveness of an actuator for controlling the drive torque. The vehicle body vibration-damping control device has a body vibration estimating unit (205) for estimating a sprung mass behavior of a vehicle body based on input information during travel, and a torque command-value computing unit (206) for computing a correction torque value for correcting a drive torque command value applied to an engine (106) when the sprung mass behavior is controlled. The torque command-value computing unit (206) has regulator and tuning units (308, 309, 310) for calculating the correction torque value based on the result of estimating the sprung mass behavior, and a nonlinear gain amplifying unit (313) for amplifying the absolute value of the correction torque when in a region where the positive or negative attribute of the calculated correction torque value is reversed, and using the amplified value to correct the drive torque command value.

摘要:
An sprung vibration damping for suppressing sprung vibration which is generated to a vehicle 1 by an input from a road surface to wheels 20 provided with the vehicle 1 by controlling a torque of a motor 10, and the sprung vibration damping is subjected to a restriction including a prohibition in response to a state of a battery 14, which supplies power to the motor 10, such as a voltage and a temperature of the battery or a state of a control, which affects the power of the battery 14, such as a charge/discharge amount feedback control and the like. With the operation, the sprung vibration damping can be restricted in a state in which there is a possibility that it is difficult to appropriately execute the sprung vibration damping, in a state in which the battery 14 is liable to be deteriorated, and further in a state in which there is a possibility that the sprung vibration damping interferes with the other control. Accordingly, the sprung vibration damping can be executed in a state that the control is compromised as necessary, and thus the sprung vibration damping and the other control can be properly executed. As a result, it can be suppressed that the other control is under the influence of the execution of the sprung vibration damping control.

摘要:
In a process for enhancing the safety and/or comfort of a motor vehicle, (a) data are generated by a vehicle controller or a group of corresponding controllers provided to control a safety-enhancing function, such as a brake controller and/or driving dynamics controller, a restraining system controller, an electronic steering controller, a chassis controller, an engine controller or a comfort function controller, and the control data are logically combined with data from a navigation system or with cartographic data, the navigation system comprising cartographic data; (b) the cartographic data are used to determine a present danger value, together with sensory information sensed directly or indirectly in the vehicle about the present driving state; and (c) interventions in the groups of safety-enhancing functions take place depending on the danger value. In particular, an optical, acoustic or haptic warning is generated in addition to or instead of the intervention, in order to warn the driver.

The present invention is directed to a wheel grip factor estimation apparatus, which includes a steering factor detection unit for detecting at least one of steering factors including a steering torque and steering effort applied to a steering system extending from a steering wheel to a suspension of a vehicle, an aligning torque estimation unit (M6) for estimating an aligning torque produced on at least a wheel of the vehicle on the basis of the steering factor detected by the steering factor detection unit, and a vehicle state variable detection unit for detecting a state variable of the vehicle. The apparatus further includes a wheel factor estimation unit for estimating at least one of wheel factors including a side force and slip angle applied to the wheel on the basis of the vehicle state variable, and a grip factor estimation unit (M12) for estimating a grip factor of at least a tire of the wheel, in accordance with a relationship between the estimated alignment torque and the estimated wheel factor.
摘要:
An automotive electronic control unit connectable to on-board automotive sensors/systems via an on-board automotive communication network to receive automotive data and programmed to process motor vehicle data to enhance motor vehicle driver awareness of motor vehicle degree of proximity to the motor vehicle roadholding limit. To this purpose, the automotive electronic control unit is programmed to compute current accelerations to which the moto vehicle is subject, compute a motor vehicle roadholding limit, and cause a motor vehicle display to provide the driver with a visual feedback of the degree of proximity of the motor vehicle to the roadholding limit.
