CONTROL DEVICE FOR VEHICLE, CONTROL METHOD, NON-TRANSITORY COMPUTER- READABLE STORAGE MEDIUM, MANAGER, AND VEHICLE
A control device installed in a vehicle comprising an electronic control unit configured to: accept a plurality of first requests from a driving assistance system; arbitrate the first requests; calculate a second request that is a physical amount that differs from the first requests based on a result of arbitration in which the first requests are arbitrated; and distribute the second request to at least one of a plurality of actuator systems, wherein the electronic control unit is configured to, when there is the first request requesting a driving force exceeding a first driving force necessary for recovery from a fuel cut state, perform arbitration such that an actual driving force generated by the vehicle is no greater than the first driving force, until reaching a driving force lower limit realizable by a powertrain actuator included in the actuator system at a current gear ratio.
VEHICLE CONTROL DEVICE
A vehicle control device configured to control a driving motor coupled to a wheel of a vehicle includes a motor controller and a driving mode determiner. The motor controller is configured to control the driving motor so that the driving motor enters a regenerative state while the vehicle is coasting and stops accelerating. The driving mode determiner is configured to determine whether the vehicle is in a first or second driving mode. In the first driving mode, a driving operation strength is low and the vehicle behavior is slow and gentle. In the second driving mode, the driving operation strength is high and the vehicle behavior is quick and active. When the vehicle stops accelerating in the second driving mode, the motor controller is configured to make a regenerative torque of the driving motor smaller than when the vehicle stops accelerating in the first driving mode.
POWER SAVINGS FOR REMOTE CONTROL DEVICE
A method is provided for Bluetooth Low Energy (BLE) communication between a remote control device comprising a peripheral BLE device and a controller on a materials handling vehicle comprising a central BLE device. The method comprises: polling via a plurality of connection requests, by the central BLE device, communicated with the peripheral BLE device with which the central BLE device is paired. The peripheral BLE device comprising one or more activatable switches. Based on the status of the one or more activatable switches, the peripheral BLE device sending reply messages to at least a portion of the plurality of connection requests in accordance with at least one of a first or a second communication operating mode. When operating in the first communication operating mode, the peripheral BLE device replies to only a portion of the plurality of connection requests, wherein each reply message is indicative of the status of the one or more activatable switches.
Method and apparatus for assisting in the maintenance of a vehicle speed within a speed range, and a vehicle comprising such an apparatus
Method and apparatus for maintaining a speed of a vehicle within a target speed range. A plurality of coasting profiles are generated for the vehicle, each having an initial speed and a starting point on a predicted vehicle path. Each coasting profile represents a predicted vehicle speed over a time and/or distance from the starting point and is generated based on a geometry of at least a portion of the predicted vehicle path. At least one of the coasting profiles that maintains the speed of the vehicle within the target speed range is identified. A prime mover of the vehicle is controlled to place the vehicle into a coasting mode in accordance with the at least one identified coasting profile. Alternatively, feedback is provided to a user to place the vehicle into a coasting mode, such that the vehicle will coast in accordance with the at least one identified coasting profile.
DRIVING FORCE CONTROL DEVICE
The driving force control device includes: a requested driving force calculation unit configured to calculate requested driving force requested to the vehicle, in a coasting state where neither an accelerator operation nor a brake operation is performed by a driver; a power train control unit configured to control a gear ratio of the power train on the basis of the requested driving force and driving force that is achieved by the power train in the coasting state; a braking force calculation unit configured to calculate braking force required for achieving the requested driving force, when the requested driving force is smaller than driving force that is achieved by the power train at a gear ratio set by the power train control unit; and a brake control unit configured to cause the brake to generate the braking force calculated by the braking force calculation unit.
Vehicle control apparatus
A control apparatus for a vehicle having a step-variable transmission. The control apparatus includes: a shift control portion to temporarily increase an input torque of the step-variable transmission beyond a required value, the shift control portion commanding an engaging-side coupling device which is the coupling device placed in a released state, to be brought into an engaged state, when the input speed has been raised to a predetermined value; and a torque increasing amount setting portion to set an amount of increase of the input torque of the step-variable transmission beyond the required value, such that the amount of increase is smaller when a rate of change of a running speed of the vehicle is relatively low than when the rate of change is relatively high, the rate of change of the running speed having a negative value in a decelerating state of the vehicle.
METHOD OF MOVING AUTONOMOUS VEHICLE AFTER ACCIDENT
A method of moving an autonomous vehicle to a safe zone after an accident is provided. The method includes: setting a threshold which is a criterion for determining a failure of a chassis system; determining whether a failure occurs by using the threshold; determining a control mode of twin clutches or a braking system; designating avoidance speed level in accordance with whether a following vehicle approaches; and setting a target trajectory to a safe zone and then generating braking torque on left and right wheels or controlling distribution of driving torque through the twin clutches in order to move the autonomous vehicle at the avoidance speed along the target trajectory.
Driving assistance apparatus
A driving assistance apparatus can execute a deceleration assistance control, when there is a deceleration target ahead, of the vehicle in a course thereof. The driving assistance apparatus is provided with: a recognizer configured to recognize a surrounding situation of the vehicle; and a controller programed to execute the deceleration assistance control when a predetermined condition is satisfied. The controller is programed to suppress execution of the deceleration assistance control if a road as the recognized surrounding situation has a high extent of a downgrade, in comparison with a situation in which the road has a low extent of the downgrade.
Method and apparatus for controlling cruise of vehicle, electronic device, and storage medium
The present application discloses a method for controlling cruise of a vehicle. The method includes: acquiring a pre-established three-dimensional trajectory map of the vehicle from a starting point to a destination; acquiring current positioning information of the vehicle; intercepting a target trajectory at a preset distance currently ahead of the vehicle from the three-dimensional trajectory map according to the current positioning information; acquiring a target point from the target trajectory according to the current positioning information; acquiring a wheelbase and a current speed of the vehicle, and calculating an angle that front wheels of the vehicle are required to rotate, according to the target point, the current positioning information, the wheelbase, and the current speed; controlling a movement of the vehicle according to the angle.
Vehicle having controllable target driving force
A vehicle includes a drive device for traveling, and a control device configured to control the drive device so that the vehicle travels with a target driving force based on an accelerator operation amount. The control device is configured to set the target driving force such that a change in the target driving force with respect to a change in the accelerator operation amount is gentler in a case where steady traveling is desired as compared with a case where the steady traveling is not desired. Therefore, in a case where the steady traveling is desired, a variation of a vehicle speed with respect to a slight variation of the accelerator operation amount can be gentle and continuous steady traveling can be facilitated.
