摘要:
A vehicle comprises management and control means associated to onboard systems and/or to a driving input interface and/or to the engine and/or powertrain and/or to at least one wheel and/or to the chassis, such management and control means being capable of: determining a multiplicity of aggregated command outputs, each of said aggregated command outputs comprising command parameters and defining an overall vehicle configuration status/mode; detecting one or more dynamic parameters relating to a vehicle movement and/or overall status and/or condition; and selectively prioritize each of said aggregated command outputs conditionally on the fact that one or more of said dynamic parameters are exceeding a threshold and/or a minimum or maximum safety value, the vehicle command parameters being changed according to said prioritization of said aggregated command outputs.

An air brake system is provided for using the air resistance of a car (1) to produce energy and for simultaneously braking the car (1). The air brake system comprises an air intake port (2) having an open and a closed position. The air intake port (2) can be arranged, for instance, on the car (1) grille or on the sides of the car (1). The air intake port (2) is connected to an air guiding channel (4) disposed inside of the car (1), preferably in the hood compartment or engine bay thereof. The air entering the air intake port (2) in its open position and being guided through the air guiding channel (4) acts on energy conversion means being configured to convert the kinetic energy of the moving air into a different usable form of energy. Preferably, the energy conversion means comprise a rotatable fan (5) and a generator (6). The fan (5) is arranged inside of the air guiding channel (4) so that air entering the air intake port (2) in its open position and being guided through the air guiding channel (4) passes by the fan (5) and causes a rotating motion thereof. The fan (5) is operatively connected to the generator (6) for converting the rotational energy of the fan (5) and, thus, ultimately the energy of the air entering via the air intake port (2) in its open position and moving through the car (1) via the air guiding channel (4) into electric energy, which can be stored, for instance, by a battery of the car (1). The inventive air brake system, thus, provides for the advantage that in addition to using an increased air resistance for braking the car (1) this braking action is also producing energy that can be re-used by the car (1).

A contactor assembly (54) having contacting head portion (56) is mounted on a vehicle (10) and a receiving device (64) is mounted on a load transfer station (12). The contactor assembly (54) and receiving device is provided for transferring electrical energy from a source of electrical energy (28) between the load transfer station (12) and the vehicle (10) and improves the flexibility of load transfer station (12) location and relocation. The contacting head portion (56) is transversely movable between first and second spaced apart locations relative to the vehicle (10) and into engagement with the receiving device (64). A sensing device (70) is provided for sensing the position of the vehicle (10) relative to the load transfer station (12) and delivering an actuator control signal to an actuating device (108) in response to the contacting head portion (56) and the receiving device (64) being aligned for mating engagement. The actuating device (108) moves the contacting head portion (56) from the first position to the second position in response to the receiving of the actuating control signal. The contactor assembly (54) is particularly suited for use on an automatic guided vehicle (10).

An electric taxiing system of an aircraft (1) includes: a wheel (5a, 7a) of an aircraft (1); a taxiing motor (5b, 7b) which is rotated together with the wheel (5a, 7a) in landing of the aircraft (1) to apply breaking force to the wheel (5a, 7a) and to generate regenerative power according to the breaking force, and which rotates the wheel (5a, 7a) in taxiing of the aircraft (1); and a power supply control unit (27) which supplies the regenerative power to an electric element of the aircraft (1), the electric element (9b, 11b, 13b, 15b, 29a, 31a) being driven in order for the aircraft (1) to perform landing or re-takeoff after cancelling landing.
摘要:
A braking system for a land vehicle with wheels for reducing the stopping distance under emergency braking comprises one or more braking elements which, when deployed, change the aerodynamic characteristics of the vehicle so as to enhance the frictional force the wheels and the road and/or increases the aerodynamic drag of the vehicle; an actuator for deploying each of the braking elements and a control system for automatically actuating the or each actuator when at least one pre-set condition is met. The braking system preferably comprises two aerodynamic braking elements which, when deployed, increase downforce (or reduce lift), increase drag and distribute the loads on the vehicle tyre contact patches more evenly. The first element is preferably a front air dam which, when deployed, bridges (or almost bridges) the gap between the underside of the front of the vehicle and the road surface. The second element is a rear spoiler which, when deployed, raises the rear, top (trailing edge) of the vehicle roof or rear deck (depending on the vehicle geometry). Either one of these elements can achieve a reduced stopping distance but both elements deployed at the same time achieves improved results. The two elements may be deployed using an electrical, pneumatic or hydraulic actuating system but in a preferred system deployment is effected by the firing of specially shaped airbags which react against the vehicle body. In a further arrangement, the airbags themselves may be to provide the braking elements. The braking elements are deployed under the control of a control system which determines when emergency braking is required.
