  • Patent number: 12280841
    Abstract: When it is determined that there is no possibility of a driver performing a predetermined steering operation for moving a host vehicle in a lateral direction without involving a change in a final travel direction, a vehicle control device sets a steering reaction force to be greater than a standard reaction force. When it is determined that there is a possibility thereof, the vehicle control device sets the steering reaction force to be smaller than the standard reaction force, and sets an increase rate of the steering reaction force relative to an increase in the amount of steering operation from a predetermined point in time after it is determined that there is a possibility of the driver performing the predetermined steering operation and before the amount of steering operation in the predetermined steering operation becomes largest to be higher than an increase rate before the predetermined point in time.

  • Publication number: 20240253695
    Abstract: A vehicle steering assist device includes a steering assist ECU. The steering assist ECU calculates a target steering angle for driving the vehicle along the road, and a target steering guide torque that guides the driver's steering so that the actual steering angle becomes the target steering angle. The steering assist ECU controls the torque applying device so that the steering guide torque becomes the target steering guide torque. The steering assist ECU acquires at least one of information on the driving environment of the vehicle and information on the state of the driver, and calculates an index value indicating the necessity of the steering guide torque based on at least one of the pieces of information. The steering assist ECU corrects the target steering guide torque based on the index value so that the higher the need for the steering guide torque, the larger the target steering guide torque.

  • Patent number: 8084178
    Abstract: A non magnetic toner comprises toner particles each containing at least a binder resin, a colorant and a wax component. The toner further comprises an inorganic fine powder. A storage elastic modulus at 110° C. (G?110) of the non magnetic toner is in a range of 2.00×104 to 2.00×105 dN/m2. A storage elastic modulus at 150° C. (G?150) of the non magnetic toner is in a range of 3.00×103 to 2.00×104 dN/m2. The toner particles are obtained by dispersing a polymerizable monomer composition containing polymerizable monomers, the colorant, the wax component and a low-molecular weight polymer into an aqueous medium, granulating the dispersed polymerizable monomer composition, and polymerizing the polymerizable monomers in granulated particles. The low-molecular weight polymer has a weight average molecular weight (Mw) measured by means of gel permeation chromatography (GPC) in a range of 2000 to 5000.
