Abstract: A vehicle comprises an internal combustion engine, a wheel propulsion shaft, wheels and a kinetic energy recovery system configured to recover and store kinetic energy of the vehicle, and restore the stored energy by propelling the wheel propulsion shaft and/or by cranking the internal combustion engine. To reduce the emissions of the vehicle, a method (100) for operating the vehicle comprises, when the vehicle operates:
- when the vehicle is not stationary, recovering (102) and storing kinetic energy of the vehicle in the KERS,
- when the vehicle is stationary, measuring (104) an energy level stored in the KERS and comparing (106) the measured energy level to a predetermined high threshold value, so that the method comprises, if the energy level stored in the KERS is above the predetermined high threshold value:
- stopping (108) the internal combustion engine, then
- when the vehicle start is required, propelling (110) the wheel propulsion shaft exclusively by the KERS.

Abstract: The invention concerns a security system circuit (100) for a vehicle (10), the security system comprising an electronic main control unit (120), at least one electronically operated switch (124, 125), which is arranged on an input line (114) of an electric load (110) of the vehicle, each electronically operated switch being controlled by the main control unit and being configured to switch between a connected configuration, where said electronically operated switch allows electricity to flow through the input line between a main electric power source (104) of the vehicle and the electric load, and a cutoff configuration, where said electronically operated switch prevents electricity from circulating through the input line between the main power source and said electric load. The system further comprises a safety switch (102), configured to be activated by a user of the vehicle, the safety switch being configured to control the main control unit, so that each electronically operated switch switches to its cutoff configuration when the safety switch is activated. Alarm means (140) are activated if after a predetermined first time interval from the moment the safety switch is activated, at least one current sensor (134) detects electric current flowing through the corresponding input line.

Abstract: The invention relates to a truck (1) adapted to transport Dangerous Goods, the truck being characterized in that it comprises:
- a chassis on which is arranged a battery (5);
- a cab (2) mounted on the chassis,
- a solar panel (3) for charging the battery (5), said solar panel (3) being arranged on cab roof (24);
- a first relay (6) configured to disconnect the battery (5) and a second relay (7), distinctive from the first relay (6), configured to disconnect the solar panel (3);
- at least one manual control element (12) located in the cab (2) configured to simultaneously open the first (6) and second (7) relays and
- a crash sensor (4) for detecting a crash situation and
- an electronic control unit configured to disconnect the second relay (7), said electronic control unit being connected to the crash sensor (4) so that the crash sensor (4) sends a signal to the electronic control unit when a crash situation is detected.
