Abstract: A brake squeal control device is proposed in which specific control for reducing brake squeals can be carried out to meet the will of a driver, and squeal control conditions for starting squeal reduction can be set individually to meet the requirements of drivers. Signals from wheel speed sensors, which indicate travel state, a hydraulic pressure sensor in a hydraulic circuit, which indicates the braking state, interior and exterior temperature sensors, which indicate the temperature state, and a manual switch operated by the will of a driver are sent to a control circuit. Conditions when squeals which the driver wishes to reduce or eliminate are produced, are stored in the control circuit, and when certain data are prepared, thereafter, by detecting the conditions at the time of generation, automatic squeal control is carried out.

Abstract: A brake squeal control device is proposed which carries out squeal control by specifying travel state and temperature conditions in which brake noise tends to be produced. The brake squeal control device is adapted to feed detection signals from a sensor group that indicates the travel state of the vehicle from a stepping force sensor or wheel speed sensors, and a sensor group that indicates the temperature state from an engine cooling water temperature sensor, a car compartment temperature sensor, a caliper temperature sensor or an outer air temperature sensor to a control circuit. If conditions corresponding to an nullin-the-coldnull and nullfirst-in-the-morningnull states are detected by computing in the control circuit, a solenoid valve is turned on and off to suppress brake squeals.
