Problems solved by technology
However, when the on-board battery and / or other energy storage devices can no longer provide usable power, the on-board controller immediately changes back to only basic operating functions, making the driver feel uncomfortable and affecting the stability of the vehicle more or less operating capacity

Embodiment Construction
[0028] Hereinafter, embodiments and modifications of the present invention will be described with reference to the drawings.
[0029] refer to Figure 1 to Figure 5A and 5B describe the first embodiment. figure 1 A rough configuration of a steering controller 1 to which the present invention is applied is shown in a block diagram.
[0030] In addition to the steering controller 1, the vehicle according to the present invention is equipped with a torque sensor 51, a speed sensor 52, a battery 53, a steering motor 54, a steering drive mechanism 55, and a steering wheel (i.e., a handle) 56 operated by a driver on the vehicle. .
[0031] The steering controller 1 is installed, for example, in a vehicle such as a passenger car, and is used to detect a force applied to the steering wheel 56 from the outside (ie, a driver's steering force or a force as a disturbance or noise) to selectively amplify Or drive the steering motor 54 in a manner of attenuating external force. For exam...

controller (1) controls an on-vehicle device has an operating member (55) operated by a driver to receive a driver' s operating force and an assisting mechanism (PS) giving an assisting force to the operating member (56). This mechanism is powered by an on-vehicle battery (53). The controller detects forces applied to the device and calculates a control amount giving the assisting force to the device based on results detected by the force detector (51). The control amount is calculated every type of the applied forces (21,22,23,31) whose frequency bands are at least partly different from each other. The controller (1) drives the assisting mechanism (PS) based on the control amount and detects an operating state of the battery (53). The controller (1) adjusts the control amount such that, as the calculated battery state decreases in a powering function of the battery, the control amount for, of the applied forces, a specified force having specified frequency components is monotonously reduced (24,25,26,32).
Description
technical field [0001] The present invention relates to an on-board control device for controlling individual electronic devices in a selective manner so as to allow their control state to be selected according to the relationship between the vehicle's power consumption and the degree of influence of said control on the vehicle's motion stability. Background technique [0002] There are various electronic devices installed in the vehicle, which need to be controlled according to how the vehicle is moving. These electronic devices include power steering equipment and brakes. Power steering equipment requires a steering controller. As for the braking device, a brake assist control device is required for a vacuum booster and a regenerative braking device for brakes in a hybrid vehicle. [0003] The power steering apparatus includes a steering motor for providing a steering assist force to a steering wheel (ie, a handle operated by a driver) in response to a steering force app...
