Method and device for diagnosing in a motor vehicle a driver's fitness drive

A method is for diagnosing the driving capability of a driver of a motor vehicle, in which changes in driver condition are ascertained from physiological measured values derived from the driver while driving in the vehicle and evaluated, and if the changes are serious, a warning is issued or remedial actions are initiated, wherein the physiological measured values ascertained while driving in the vehicle are combined by a corresponding expert system with health-relevant data for the driver ascertained in stationary fashion, and with data indicating driver stress that are estimated in particular from the instantaneous traffic situation and instantaneous operating state of the vehicle, and the changes in the driver's condition are weighted with the estimated driver stress and interpreted. An apparatus for performing the method is characterized in that the expert system is implemented in an onboard computer of the vehicle which is connected via a bus internal to the vehicle to a mobile driver condition sensor suite that supplies the physiological measured values, to a memory / transfer medium that delivers the biographical data and / or the health-relevant data ascertained in stationary fashion, and to an ACC system and driving direction system internal to the vehicle.

CAN bus instrument vehicle controlling information processing method for mixed power passenger car

The present invention relates to a CAN bus meter vehicle controlling information processing method for a hybrid power driven passenger car, which belongs to the automobile electronic intelligent meter field. The method is by the LAN connection of the CAN bus interface unit inside a singlechip and a standard controller arranged in the vehicle to receive the information data packet sent on the CAN bus network by each controller in the vehicle; by controlling the singlechip program to collect the vehicle controlling information of the hybrid power driven passenger car; by calculating and concluding to analyze out the integrative information and the history operation state of the stored vehicle; by the lattice type color liquid crystal screen to realize animated cartoon in the form of characters, sliding bar patterns, and flowing vectorgraphs; by the form of dynamic coordinate point and the dynamic movement curve in the two dimensional coordinate chart to display the vehicle controlling information of the hybrid power driven passenger car. The prevention improves the safety and the economical effect of the vehicle greatly, and is applicable for the characteristic of complex state and large information volume of the mechanical and electrical hybrid power driven passenger car.

Loudspeaker reliability test device

The invention discloses a loudspeaker reliability test device comprising a machine box which is internally provided with a computer system. The computer system is provided with a LabView processing module and an audio card. The loudspeaker reliability test device also comprises a test card which is arranged in the machine box and connected with the computer system. The test card is provided with multipath of test channels which are formed by audio power amplifier chips, sampling resistors and loudspeaker connecting terminals in a series-connection way. The input end of each audio power amplifier chip is connected with the output end of the audio card. The test card is also provided with a voltage and current acquisition module and a single-chip microcomputer. Two ends of each sampling resistor and each loudspeaker connecting terminal are connected with the input end of the voltage and current acquisition module. The output end of the voltage and current acquisition module is connected with an I / O of the single-chip microcomputer. The I / O of the single-chip microcomputer is also connected with a mute pin of each audio power amplifier chip. A serial port of the single-chip microcomputer is connected with the computer system. The loudspeaker reliability test device is concise in structure, convenient to operate and maintain, stable and reliable and long in the service life.
