An indicator is provided in a vehicle for indicating necessity of change of a fuel vapor absorber in a venting line of a vehicle tank, especially a methanol tank for fuel cell vehicles.

A clutch plate and a clutch assembly for use in a powertrain of a vehicle, the clutch plate being configured to be connected for common rotation with a driven shaft extending in an axial direction, the clutch plate including a support member and a first friction member attached thereto, the first friction member having a first friction surface configured to face and selectively engage a corresponding second friction surface of a flywheel, the clutch plate further including an electrically conducting element extending from the first friction surface toward the support member in a direction having an axial component, the electrically conducting element being configured to be electrically connected to a terminal, so that, upon engagement of the first and second friction surfaces, an electric signal may be passed between the flywheel and the terminal via the electrically conducting element.

A vehicle collision avoidance assistance device is configured to perform forced braking or forced steering when a driver's vehicle has a possibility of colliding with an object ahead of the driver's vehicle, acquire at least one of information related to a condition of the driver's vehicle and information related to a situation around the driver's vehicle, determine, based on the acquired information, whether a request condition for requesting execution of the forced steering is satisfied and whether a forbiddance condition for forbidding the execution of the forced steering is satisfied, perform the forced braking when the request condition is not satisfied regardless of whether the forbiddance condition is satisfied, perform the forced steering when the forbiddance condition is not satisfied and the request condition is satisfied, and perform the forced braking when the forbiddance condition is satisfied though the request condition is satisfied.

A method for manipulation detection of a technical device, i.e., an exhaust gas after treatment device in a motor vehicle, including: providing an input vector including system variable(s) and including at least one control variable for an intervention in the technical device for successive time steps; using a data-based manipulation detection model to generate a corresponding output vector as a classification vector in each time step for each input vector, each output vector indicates a classification of a monitored variable in value ranges, for the input vector; providing an actual monitored variable based on at least one measured value in the successive time steps; creating a measurement classification vector from the actual monitored variable for each time step; detecting a manipulation as a function of the measurement classification vector and a first and a second comparison vector for time step(s) of the time window.

The present disclosure relates to systems, devices, and methods for analyzing health of vehicle batteries. Vehicle batteries tend to degrade over time. The described systems, devices, and methods quantify this degradation (or quantify remaining health of the battery) by comparing average energy used to charge or discharge the battery by a charge level unit to a nominal quantity of energy used to charge or discharge a battery in optimal health by a charge level unit. Charge data for previous charge events of the vehicle battery can be used in the calculation, and can be filtered by identifying qualified charge events based on at least one of a number of metrics. Usage data for previous usage events of the vehicle battery can be used in the calculation, and can be filtered by identifying qualified usage events or subgroups of usage event based on at least one of a number of metrics.

A method for determining road loads includes preparing a road map (15) that contains information about the local configuration of a plurality of roads. For each of a plurality of vehicles (1) a vehicle location is determined and at least one vehicle location signal (So) that characterizes the location of the vehicle concerned is generated. Using the vehicle location signal (So) and the road map, the vehicles (1) are assigned to the roads. For each vehicle (1) a vehicle load mass is determined and at least one vehicle load mass signal (Sm) that characterizes the vehicle load mass is generated. At least one road loading signal (Sb) that characterizes a road load is generated for each road using the vehicle load mass signals (Sm) of the vehicles (1) assigned to it.
