Slip-stop device for preventing slipping of vehicle wheels
First Claim
1. A slip-stop device for a vehicle comprising a tank in which is stored a liquid, a heater for heating the liquid in said tank to a high temperature, a sprayer provided near a road wheel of the vehicle for spraying the high-temperature liquid in discontinuous flows or droplets, a sensor unit for producing signals indicating the state of a road surface on which the vehicle is traveling, and a control unit for controlling said heater and said sprayer, said control unit being arranged to determine whether the road surface is frozen based on the signals from said sensor unit and, if the road surface is determined to be frozen, activate said sprayer to spray the high-temperature liquid on the road surface, thereby increasing the roughness of the road surface.

Abstract
A slip-stop device to be mounted on a vehicle is proposed. It includes a tank in which is stored a liquid. The liquid is heated by a heater. A control unit detects the temperature of the road surface on which the vehicle is traveling based on temperature information from temperature sensors to determine whether the road surface is frozen, and whether a particular wheel of the vehicle is slipping. If it determines that the road surface is frozen and the wheel is slipping, the control unit activates a motor-driven pump to spray heated liquid on the frozen road to melt the ice covering the road, thereby increasing the roughness of the road surface. The liquid should be non-freezing liquid such as water that has been subjected to non-freezing treatment or alcohol.

- 1. A slip-stop device for a vehicle comprising a tank in which is stored a liquid, a heater for heating the liquid in said tank to a high temperature, a sprayer provided near a road wheel of the vehicle for spraying the high-temperature liquid in discontinuous flows or droplets, a sensor unit for producing signals indicating the state of a road surface on which the vehicle is traveling, and a control unit for controlling said heater and said sprayer, said control unit being arranged to determine whether the road surface is frozen based on the signals from said sensor unit and, if the road surface is determined to be frozen, activate said sprayer to spray the high-temperature liquid on the road surface, thereby increasing the roughness of the road surface.
- 2. A slip-stop device for a vehicle comprising a tank in which is stored a liquid, a pressurizing unit for pressurizing the liquid in said tank to a high pressure, a sprayer provided near a road wheel of the vehicle for spraying the pressurized liquid in discontinuous flows or droplets, a sensor unit for producing signals indicating the state of a road surface on which the vehicle is traveling, and a control unit for controlling said pressurizing unit and said sprayer, said control unit being arranged to determine whether the road surface is frozen based on the signals from said sensor unit and, if the road surface is determined to be frozen, activate said sprayer to spray the pressurized liquid on the road surface, thereby increasing the roughness of the road surface.
- 3. A slip-stop device for a vehicle comprising a tank in which is stored a liquid, a pressurizing unit for pressurizing the liquid in said tank to a high pressure, a heater for heating the liquid to a high temperature, a sprayer provided near a road wheel of the vehicle for spraying the pressurized high-temperature liquid in discontinuous flows or droplets, a sensor unit for producing signals indicating the state of a road surface on which the vehicle is traveling, and a control unit for controlling said pressuring unit, said heater and said sprayer, said control unit being arranged to determine whether the road surface is frozen based on the signals from said sensor unit and, if the road surface is determined to be frozen, activate said sprayer to spray the pressurized high-temperature liquid on the road surface, thereby increasing the roughness of the road surface.
