A system for automatically stopping an autonomous vehicle, in which the autonomous vehicle includes a primary brake and a secondary brake controlled by least one control module or different control modules. The system includes: an error detection module configured to detect an error in the control of the primary brake or the secondary brake by the one control module or the different control modules; and a supplemental control module configured, upon a detected error by the error module, to cause a stop of the autonomous vehicle using the primary brake or the secondary brake.

A method of controlling a vehicle accessory includes determining a transmission of a vehicle is in a non-park setting; in response to determining the transmission of the vehicle is in the non-park setting, receiving speed data indicative of a speed of the vehicle; determining a speed to operate the vehicle accessory based on the vehicle speed; comparing the determined speed to operate the vehicle accessory to a speed threshold; and in response to determining that the determined speed is below the speed threshold, providing a command to the vehicle accessory to one of deactivate the vehicle accessory or operate the vehicle accessory at a reduced operating state relative to a current operating state of the vehicle accessory.

A power split and creep drive system for street sweeper or like specialty vehicle having a single engine is disclosed. The system intends to retrofit and convert on-highway truck chassis into specialty vehicles capable of performing work function and moving at creeping speed, such as a street sweeper. It includes a hydraulic work circuit or power-take-off (PTO) port, a planetary gear set, a hydraulic system comprising pumps and motors to drive the working devices and balance the demand between propulsion and work function such as sweeping. The planetary gear set includes an input shaft connecting to a transmission output shaft of the chassis, a first output shaft connecting to a hydraulic machine, and a second output shaft to vehicle propulsion drive shaft.

A control device for a vehicle is provided with a catalyst warmup control part supplying electric power to a conductive base to warm up a catalyst device if the temperature of the conductive base is less than a predetermined temperature and the state of charge of the battery is less than a second state of charge larger than a first state of charge when the state of charge of the battery is equal to or greater than the predetermined first state of charge and a driving mode of the vehicle is set to an EV mode in which at least the output of the rotary electric machine is controlled to make the vehicle run. The catalyst warmup control part sets the second state of charge so that the second state of charge becomes larger in the case where the resistance value of the conductive base is large compared to when it is small.

A controller of a vehicle, while the vehicle is within a predefined geofenced region and responsive to the vehicle entering park, increases a maximum state of charge threshold for the battery and decreases a minimum state of charge threshold for the battery. The controller also, while the vehicle is located within the predefined geofenced region and responsive to the vehicle exiting park, decreases the maximum state of charge threshold and increases the minimum state of charge threshold.

An agricultural sprayer includes a computing system configured to receive a first input associated with a target application rate at which agricultural fluid is to be dispensed onto the field. Moreover, the computing system is configured to receive a second input associated with a turn being made or to be made by the sprayer. Additionally, the computing system is configured to determine a maximum ground speed for the turn at which a selected nozzle dispenses the agricultural fluid onto the field at the target application rate based on the received first and second inputs. Furthermore, when the turn is being made, the computing system is configured to control an operation of the sprayer such that the ground speed of the sprayer is at or below the determined maximum ground speed.
