  • Patent number: 8569985
    Abstract: In a wiper control apparatus, a water drop detector outputs an output signal in accordance with water drops adhering to a windshield of a vehicle. When a traveling determination portion determines that the vehicle is traveling, a first level setting portion sets a sensitivity for detecting the output signal to a first sensitivity. When the traveling determination portion determines the vehicle is not traveling, a second level setting portion sets the sensitivity for detecting the output signal to a second sensitivity that is larger than the first sensitivity. A water drop adhesion determination portion determines that water drops adhere to the windshield when a determination waiting time elapses in a state where detection of the output signal continues. A driving control portion controls a wiper driving portion to drive the wiper when the water drop adhesion determination portion determines that water drops adhere to the windshield.

  • Patent number: 5483133
    Abstract: A control system for opening or closing an opening-closing member when a foreign material is caught by the opening-closing member. The event that the opening-closing member catches the foreign material is decided on the basis of a driving state of a motor for driving the opening-closing member such as a power window. For example, the event that the event of catching the foreign material is decided when a driving acceleration or a driving velocity is less than a predetermined threshold X or Y, respectively. Each of the thresholds X and Y is set basically on the basis of the previous driving acceleration and velocity of the opening-closing member. The thresholds X and Y are corrected on the basis of a condition exerting an influence upon the driving state of the motor, for example, on the basis of a driving voltage or a resistance to a sliding movement of the opening-closing member.

  • Patent number: 5094115
    Abstract: An operation apparatus for a vehicle automatic transmission mechanism includes first and second actuators, connected in parallel with a hydraulic valve, for driving the hydraulic valve to switch a travel range of an automatic transmission mechanism, a control unit for controlling the first and second actuators, and a transmission operation unit for outputting a range signal indicating a presently set travel range to the control unit. The transmission operation unit includes a stroke contact type operation switch on which travel ranges to be set are sequentially aligned along a predetermined path.
