Update data is acquired from an external instrument (10) to a master device (1), and the update data acquired to the master device (1) is written to a data storage side of a storage unit (201) included in an electronic control device (2) according to an instruction from the master device (1). After the update data is written to the data storage side, a first detection unit (102) is used to determine whether or not a vehicle is parked, and when a determination is made using the first detection unit (102) that the vehicle is parked, an instruction is given to the electronic control device (2) to activate a program stored in the data store side and rewritten with the update data. Then, when the program is activated according to the instruction to activate the program, a second detection unit (202) different from the first detection unit (102) is used to determine whether or not the vehicle is in a parking state, and when the second detection unit (202) is used to determine that the vehicle is in the parking state, the program is activated, thereby updating the program for the vehicle.

A fire fighting vehicle includes a chassis, tractive elements coupled to the chassis, a pump coupled to the chassis, a discharge fluidly coupled to the pump, an accessory module coupled to the chassis, and an electric motor coupled to the chassis, the pump, and the accessory module. The accessory module is configured to receive a mechanical energy input and provide at least one of electrical energy or fluid energy. The electric motor is configured to provide mechanical energy to drive (a) the pump to provide fluid to the discharge such that the fluid is expelled from the discharge and (b) the accessory module to provide the at least one of electrical energy or fluid energy.

A vehicle control interface includes: a memory in which a program including a predetermined API defined for each of signals is stored; and a processor configured to perform interfacing between an autonomous driving system and a vehicle platform by executing the program. The vehicle platform is configured to be activated in response to one of a first and second activation commands. The first activation command is a command transmitted from the autonomous driving system to the vehicle platform via the vehicle control interface. The second activation command being a command in response to a manual operation on the vehicle platform. The processor is configured to, when the vehicle platform is activated in response to the first activation command, reduce effectiveness of the manual operation on the vehicle platform compared to when the vehicle platform is activated in response to the second activation command.

An unmanned detection unit detecting that the driver is away from the driver's seat, a vehicle speed detection unit detecting the vehicle speed of the vehicle, a vehicle speed determination unit determining whether the vehicle speed detected by the vehicle speed detection unit in a state where the driver is detected by the unmanned detection unit in a state where the driver is away from the driver's seat of the vehicle is equal to or lower than a predetermined vehicle speed, a braking control unit executing braking control for reducing the vehicle speed by determining that the vehicle speed exceeds the predetermined vehicle speed in a state where the driver is away from the driver's seat of the vehicle, and a parking control unit executing parking control for operating the parking mechanism when the vehicle speed becomes equal to or lower than the predetermined vehicle speed after executing braking control.

In the vehicle control device, when the accelerator pedal is operated while the electric parking brake of the vehicle is operating, the determination unit determines, based on the open/closed state of the vehicle door, the wearing state of the seat belt, and the operating state of the brake pedal, It is determined whether the operation of the accelerator pedal is an erroneous operation. The control unit executes at least one of control for actuating the hydraulic brake of the vehicle and control for suppressing the driving force of the vehicle when it is determined that the operation of the accelerator pedal is an erroneous operation.

An electrified airport rescue fire fighting (ARFF) vehicle includes at least one front axle, two rear axles, a water tank having a maximum water capacity of greater than or equal to about 3,000 gallons, a battery pack, and one or more electric motors configured to receive power from the battery pack to facilitate accelerating the ARFF vehicle from 0 to 50 miles-per-hour in 25 seconds or less while the water tank is at the maximum water capacity.

A vehicle control interface includes: a memory in which a program including a predetermined API defined for each of signals is stored; and a processor configured to perform interfacing between an autonomous driving system and a vehicle platform by executing the program. The vehicle platform is configured to be activated in response to one of a first and second activation commands. The first activation command is a command transmitted from the autonomous driving system to the vehicle platform via the vehicle control interface. The second activation command being a command in response to a manual operation on the vehicle platform. The processor is configured to, when the vehicle platform is activated in response to the first activation command, reduce effectiveness of the manual operation on the vehicle platform compared to when the vehicle platform is activated in response to the second activation command.

A method performed by a control unit for handling safe stop mode of a vehicle. The control unit obtains an activation request for activating the safe stop mode. When the activation request has been obtained, the control unit verifies that all safety conditions of the vehicle are fulfilled. The control unit activates the safe stop mode when the activation request has been obtained and when all safety conditions are fulfilled. The control unit triggers at least one light source to be turned on when all safety conditions are fulfilled. After the safe stop mode has been activated, the control unit obtains an inactivation request for inactivating the safe stop mode of the vehicle. The control unit inactivates the safe stop mode of the vehicle when the inactivation request has been obtained.

A control system includes a braking system operably coupled to a wheel assembly to apply braking force when actuated responsive to operation of a brake pedal, a propulsion system to apply positive torque for propulsion responsive to operation of an accelerator pedal, and a gear selector to select an operating state of the vehicle when the gear selector is in an unfaulted state. The operating state is a selected one of park and drive states. The braking system applies a holding force in the park state and the propulsion system enables application of the positive torque in the drive state. The control system further includes a park status backup controller that detects actuation of the brake pedal, and receives information indicative of a fault state of the gear selector. In response to receiving an activation pattern during the fault state, the park status backup controller generates an operating state change instruction.

A method for determining vehicle pitch comprising a first operational state, defined by the vehicle being above a velocity threshold, during which a plurality of inputs are used to determine absolute pitch. The pitch may be calculated by integrating the longitudinal acceleration measurements to estimate the distance-averaged global attitude of the longitudinal acceleration measurements, accounting for contributions from change in vehicle speed and average gravitational acceleration due to grade. The method further comprising a second operational state, defined by the vehicle being below a velocity threshold, during which a plurality of inputs are used to determine relative vehicle pitch.
