摘要:
In a process and apparatus for braking a hybrid drive vehicle, kinetic vehicular energy is converted by the driving electric motor into electrical power, which alternatively can be absorbed by charging a traction battery or by driving a combustion engine via a generator coupled to the engine, which is functioning as a motor. According to the invention, engine braking is activated if the traction battery is fully charged, if its temperature lies outside a predetermined charging temperature range, or if the charging current due to the electrical power supplied by the driving electric motor exceeds a predetermined limit value.

The invention relates to a charge information system to support the operator of an electric vehicle or hybrid vehicle, including the input of desired parameters for charging and operating the vehicle. The charge information system according to the invention comprises an input unit for putting the desired parameters into a computing unit which determines the required remaining charging time and displays it. Defining quantities are, among others, the charging efficiency or the desired range.

The invention relates to a battery current monitoring system for traction batteries in electric vehicles and hybrid vehicles, in which battery current monitoring system the maximum battery current is monitored in order to avoid damage to the battery as a result of overheating due to excessively high battery currents and, if appropriate, the said maximum battery current is reduced to a normal value which is permitted for continuous operation. Monitoring is activated if the battery current exceeds a prescribed limit value. The battery current is however not reduced until the battery temperature exceeds a prescribed limit value. It is also proposed not to use the measured average battery temperature as the control variable, but rather to use a reference temperature calculated on the basis of heat balances for individual reaction zones of the battery. The monitoring is terminated as soon as both the average and the calculated battery temperatures drop below a prescribed uncritical value.

An arrangement with an epicyclic gearbox for driving two motor vehicle axles utilizes two inner central wheels with different numbers of teeth and engaging with a planet wheel. The inner central wheels are respectively in effective drive connection with one vehicle axle while the planet carrier of the planet wheel is connected to a centrifugal brake used as bursting protection for the epicyclic gear and a friction clutch effectively located between the planet carrier and a central wheel.

In an exhaust system for an internal combustion engine having a main exhaust conduit with a catalytic converter arranged remote from the engine and a bypass exhaust conduit which includes a start-up catalytic converter arranged close to the engine and joins the main exhaust gas conduit ahead of said remote catalytic converter, an ejector structure is arranged in the main exhaust gas conduit within a housing defining a suction chamber in communication with the bypass exhaust conduit for drawing gas through the bypass exhaust conduit into said main exhaust gas conduit whenever exhaust gas flows from the engine through the main exhaust gas conduit and a main exhaust conduit valve is arranged between the ejector structure and the junction of the main and the bypass exhaust conduits which is closed during start-up operation of the engine to thereby force the exhaust gas to flow through the suction chamber and the bypass exhaust gas conduit via the start-up catalytic converter.
摘要:
A method for controlling a drive (16) of a motor vehicle having an internal combustion engine (10) and an electric motor (24). A main transmission (16) having an output shaft (18) is connected to a driveshaft (19) of the motor vehicle, and an input shaft (14) is connected to the internal combustion engine (10). The electric motor (24) is coupled to the input shaft (14) or the output shaft (16) of the main transmission (16) by an intermediate transmission (22) having at least two transmission ratio steps. In order to accelerate the motor vehicle from rest, the drive is initially effected solely by the electric motor (24) with the intermediate transmission (22) in its lowest transmission ratio step. The drawing is then taken over by the internal combustion engine (10) before a shift operation in the intermediate transmission (22). In this case, the intermediate transmission (22) is preferably a claw shift transmission.

An exterior rearview mirror for a motor vehicle has a mirror housing, a wiper motor, and a wiper arm which is driven by the wiper motor via a wiper mechanism and bears a wiper blade for cleaning a mirror surface. The wiper mechanism generates an essentially parallel reciprocating movement of the wiper blade. It is essential here to the invention that the wiper mechanism has a first L-shaped pivot arm and a second L-shaped pivot arm which are respectively mounted rotatably in a fixed position at their elbows and are mounted rotatably, at their limbs on the wiper side, on an inner parallel wiper arm. Furthermore, an outer parallel wiper arm which is connected to the inner parallel wiper arm and bears the wiper blade is arranged on the inner parallel wiper arm. The two pivot arms are driven by the wiper motor to which they are connected in terms of drive at their limbs on the drive side.

A vehicle exhibits a dashboard having a glove compartment, the receiving space of which can be covered by a cover which is movably secured on the dashboard and which, for opening the glove compartment, is disposed so as to be movable approximately in the vertical direction within the vehicle. At least the folded airbag casing of a passenger airbag is here accommodated and fastened in a cavity of the cover, a cap covering the cavity of the cover being able to be opened as the airbag casing unfolds in the direction of the vehicle interior.
摘要:
A method of generating a pulse-width-modulated three-phase voltage or alternating voltage (2) from a direct voltage (1) by at least one converter or inverter. The direct voltage (1) is sampled with variable pulse width intervals (t1, t2, t3). This method makes it possible to suppress interfering noise in the audible range.
