A method for controlling a convoy including a pilot vehicle and a driverless vehicle is presented. It includes electronically tethering the driverless vehicle to the pilot vehicle by establishing communication between a pilot vehicle control module and a driverless vehicle control module. It further includes receiving a longitudinal control user input in the pilot vehicle control module and communicating a longitudinal motion request from the pilot vehicle control module to the driverless vehicle control module, the longitudinal motion request being indicative of the longitudinal control user input. It finally includes controlling a propulsion and braking system of the driverless vehicle in response to the longitudinal motion request received from the pilot vehicle and controlling a propulsion and braking system of the pilot vehicle, while tethered to the driverless vehicle, to maintain a target longitudinal clearance from the driverless vehicle.

WHEEL LOADER

Provided is a wheel loader capable of automatically decreasing vehicle speed without making an operator feel discomfort during a loading operation. A wheel loader 1 mounted with a torque converter type traveling drive system comprises a controller 5 configured to control shifting of a transmission 32. When a vehicle body travels forward at vehicle speed corresponding to a second speed stage set greater by one speed stage than the lowest speed stage of the transmission 32 while operating the lift arm 21 upwardly, the controller 5 sets, as a gear ratio of the transmission 32, an intermediate gear ratio between a gear ratio corresponding to the second speed stage and a gear ratio corresponding to a first speed stage, and outputs a signal for selecting a combination of a plurality of gears corresponding to the set gear ratio to each first to fifth solenoid control valves 32A to 32E.

Vehicle control device and vehicle control method

This vehicle control device comprises an autonomous driving control unit which automatically controls the stopping of a vehicle. If it is determined by a crossing determination unit that there is no crossing, the autonomous driving control unit controls the stopping of the vehicle so that the vehicle is stopped at a standard target stop position corresponding to a stop line on the basis of the positional information of the stop line, whereas if it is determined by the crossing determination unit that there is a crossing, the autonomous driving control unit controls the stopping of the vehicle so that the vehicle is stopped at a position before the standard target stop position on the basis of the positional information of the stop line.

20210221250 · 2021-07-22 ·

The present invention relates to a power management system of a pure electric vehicle powered exclusively by batteries which allows the vehicle to carry a load of up to 13 tons, where the system of the present invention is provided with five blocks: a battery system (SBAT) (3), a control and power logic unit (ULCP) (4), a traction system (STR) (5), an auxiliary system (SAX) (36), and a driver's control panel (PCM) 81, where such blocks are interconnected by two buses, CAN bus (128) and Digital/Analogical BDA (129). The battery system has two battery banks (1) and (2) in parallel which are monitored by the BMS (76). The BMS (76) checks whether the voltages at the output of the batteries are the same as the input of the inverter (8) and manages the use of the battery banks in conjunction with the eVSI (73) by operating the battery bank (1) or the battery bank (2) or both depending on the load conditions of each bank. The eVSI (73) coordinates the control and power logic unit (ULCP) (4) which, through its components, controls the flow of energy between the battery banks, the traction system (STR) (5) and the auxiliary system (SAX) (36).

AUTONOMY FIRST ROUTE OPTIMIZATION FOR AUTONOMOUS VEHICLES

Embodiments herein can determine an optimal route for an autonomous electric vehicle. The system may score viable routes between the start and end locations of a trip using a numeric or other scale that denotes how viable the route is for autonomy. The score is adjusted using a variety of factors where a learning process leverages both offline and online data. The scored routes are not based simply on the shortest distance between the start and end points but determine the best route based on the driving context for the vehicle and the user.

Vehicle and regenerative braking control system for a vehicle

A vehicle includes a torque converter bypass clutch, a wheel, a generator, and a controller. The torque converter bypass clutch is disposed between the wheel and the electric machine. The controller is programmed to, responsive to slip of the clutch exceeding a threshold during regenerative braking, energize the electric machine such that a torque being transferred from the wheel to the electric machine increases at a first rate and increase clutch pressure to decrease the slip. The controller is further programmed to, responsive to the slip decreasing to less than the threshold during the regenerative braking, adjust electric machine energization such the that torque being transferred from the wheel to the electric machine increases at a second rate that is greater than the first rate.
