Abstract: A vehicle brake hydraulic pressure control apparatus installed in a vehicle changing a drive torque transferred to a wheel during a halt, includes vehicle holding section for performing vehicle holding control that holds an actual brake hydraulic pressure applied to the wheel during a halt and storage section for storing a holdable hydraulic pressure capable of holding the halt state of the vehicle before and after the drive torque changes during a halt, in which when determining that the actual brake hydraulic pressure is less than the holdable hydraulic pressure (first hydraulic pressure P1) at a start (time t1) of the vehicle holding control, the vehicle holding section increases the actual brake hydraulic pressure to the holdable hydraulic pressure and holds the holdable hydraulic pressure.

Abstract: A vehicle brake hydraulic pressure control apparatus includes, as a controller 20, acceleration acquiring section 22 for acquiring an output value of an acceleration sensor detecting a front-rear direction acceleration of a vehicle, limiting section 23 for limiting the magnitude of the output value acquired by the acceleration acquiring section 22 within a predetermined limit value, a filter (control acceleration calculation section 24) limiting a change of a value output by the limiting section 23 in a predetermined direction, and holding section 29 for determining a holding pressure according to a value output by the filter and, based on the holding pressure, holding the braking force.

Abstract: A vehicle brake hydraulic pressure control apparatus (control apparatus 100), installed in a vehicle reducing a drive torque when the vehicle is at a halt, that includes vehicle holding control section 113 for performing vehicle holding control by holding a brake hydraulic pressure when the vehicle is at a halt. The vehicle holding control section 113 is configured to release the holding of the brake hydraulic pressure based on the accelerator operation of a driver when the vehicle is at a halt and, in the releasing of the holding of the brake hydraulic pressure, release the holding of the brake hydraulic pressure completely before the drive torque of the vehicle starts increasing.

Abstract: In order to enable a transmission to reliably perform a switching to a parking range thereof, a vehicle control device includes a shift-by-wire device which switches a shift range of a transmission mounted on a vehicle in accordance with a request by an electric signal, an acceptance unit which accepts a request for switching to a parking range of the transmission, a detection unit which detects that switching to the parking range of the transmission has been settled, and a braking device which generates a braking force when the acceptance unit accepts a request for switching to the parking range of the transmission, from the time of acceptance of the request for switching until the detection unit detects settlement of the switching to the parking range.

Abstract: Brake hydraulic pressure is appropriately prevented from becoming lower than a reference brake pressure for holding control. When a physical amount correlating with the rotational speed of an electric motor has become higher than or equal to a predetermined value, an HSA start reference pressure setting unit sets an HSA start reference pressure to a value higher than a reference brake pressure, and if the HSA start reference pressure at a time when a driver required fluid pressure has become lower than the HSA start reference pressure is higher than the reference brake pressure, an HSA required fluid pressure setting unit sets an HSA required fluid pressure at a time when the driver required fluid pressure has become lower than the HSA start reference pressure to a value higher than the reference brake pressure.
