Method for efficiently managing ignition states for keyless ignition systems for vehicles with electronic shifter and electronic securement systems
A control system and method for a vehicle is provided. The system comprises a poly-shifter, an RF Hub, a transmission control module (TCM) and a controller. The poly-shifter is configured to be moved between operating states including Park and Non-Park positions. The RF Hub supports operational features of the vehicle. The TCM determines a lock state of a parking pawl in a transmission of the vehicle and communicates the lock state to the RF Hub. The controller is configured to determine whether a driver has exited the vehicle with the poly-shifter in a Non-Park position. The controller is further configured to power down the vehicle based on the lock state of the parking pawl being in a Park position and the driver exiting the vehicle with the poly-shifter in the Non-Park position.
Power transmission control device, and power transmission or vehicle including the same
A power transmission includes a first brake, a pressure regulating valve, an accumulator, an oil temperature sensor, a second electromagnetic valve allowing supply of working oil to a piston, and a power transmission control device. The power transmission control device includes a memory relating and storing a working oil temperature and a permission time configured to allow release of the accumulator, and a receiver unit receiving a starting request. The accumulator is connected such that the working oil, in which the pressure is accumulated, can be supplied to the first brake and the piston. The power transmission control device sets a permission time corresponding to a temperature of the working oil on the basis of the memory. The working oil, in which the pressure is accumulated, is supplied to the first brake only during the permission time when restart information is received, while a vehicle performs idling stop control.
Work machine
A work machine includes an engine, a hydraulic pump, a work apparatus driver to receive a pressurized fluid, a hydraulic circuit connecting the hydraulic pump with the work apparatus driver, a control valve in the hydraulic circuit, a relief valve connected to a first portion upstream of the control valve, a drain path connected to a second portion upstream of the first portion, an on-off valve to open and close the drain path, and a controller to control the on-off valve based on a state of the engine. The controller is configured or programmed to keep the on-off valve open after detecting an operation to start the engine until detecting a start of the engine and to close the on-off valve in response to detecting the start of the engine.
Apparatus and method for controlling driving of vehicle
An apparatus for controlling a vehicle includes a vehicle state detector for detecting a vehicle state, a function unit that performs at least one vehicle function, an operation unit that enables a transmission operation to allow selection of a transmission stage from among a plurality of transmission stages, and a position adjusting unit to switch the operation unit between a first position where the transmission operation is disabled and a second position where the transmission operation is enabled, by rotating the operation unit with respect to the functional unit, based on the detected vehicle state.
Vehicle roll-away prevention
A brake interlock feature prevents release of the park mechanism unless a driver is depressing the brake pedal. This is intended to prevent the vehicle from rolling following park release. An enhanced brake interlock feature also checks to ensure that adequate brake boost is available to prevent vehicle roll before releasing the park mechanism. The feature may directly measure brake boost or may measure a quantity indirectly related to the availability of brake boost such as engine speed.
Preventive measures for a cognitive impaired user
A computing device detects that an ignition switch of the vehicle was activated, wherein the vehicle includes a navigation device. The computing device requests a destination from the navigation device. The computing device interlocking, an operation of the vehicle based on determining that the destination is not valid.
TRANSMISSION DEVICE
A transmission device is provided with a hydraulic control device, which has a pump for generating hydraulic pressure using power from a motor, and an accumulator, and which controls hydraulic pressure and supplies the hydraulic pressure to a hydraulic servo of an engagement element. The transmission device executes, when the motor that automatically stopped starts up with a request for vehicle travel: a fill control in which the hydraulic control device is controlled so that the hydraulic servo is being filled with working oil; a standby control to control the hydraulic pressure in the hydraulic servo at a standby pressure; and an engagement control to increase the hydraulic pressure in the hydraulic servo is started when the rotational speed of the motor becomes reaches or exceeds a prescribed rotational speed, after hydraulic pressure accumulated in the accumulator is released into the hydraulic circuit, so that the engagement element is engaged.
Vehicle Parking System and Method of Controlling the Same
Disclosed herein is a method of controlling a system for neutral range parking of a vehicle. The power of the vehicle is turned off based on operation of a start button when a shift range of a vehicle transmission is a P-range. It is determined whether a brake pedal is operated after the power is turned off and, when the brake pedal is determined to be operated after the power is turned off, an automatic lever solenoid valve of the transmission is operated to allow the transmission to shift from the P-range to another shift range by releasing engagement between the automatic lever solenoid valve and an engaging lever.
Control apparatus for power transmission system
At the time when a hydraulic actuator is operated to engage a dog clutch, after it is detected that a hydraulic pressure for operating the hydraulic actuator is higher than or equal to a predetermined hydraulic pressure, it is determined whether the dog clutch is not engaged. Therefore, non-engagement determination due to insufficient hydraulic pressure for operating the hydraulic actuator is prevented. Thus, at the time when the hydraulic actuator is operated to engage the dog clutch, it is possible to prevent consumption of time to engage the dog clutch due to unnecessary re-engagement operation.
