The 1st ＞ of ＜
In the 1st, the functional safety sensor 32 of Fig. 3 is the sensor of vehicle speed pulse, and functional safety is by this with data
The initial data of vehicle speed pulse detected by sensor.Fig. 5 is an exemplary figure of the initial data for indicating vehicle speed pulse.
As shown in figure 5, if mobile unit related with vehicle speed pulse etc. is in normal condition (normal signal of Fig. 5), the wave of waveform
The interval at peak (pulse) is substantially stationary, if but mobile unit related with vehicle speed pulse etc. be in abnormality (the abnormal letter of Fig. 5
Number), then the interval of wave crest will produce deviation.
Therefore, it in existing data transmission and processing device, has following structure：The monitoring unit being connected with versabus
(not shown) receives the data of the vehicle speed pulse after data-reduction from versabus, and between the wave crest based on the vehicle speed pulse
Every judged with the presence or absence of abnormal this vehicle.According to this structure, even from the vehicle speed pulse after data-reduction

Such as can be based on the waveform of vehicle speed pulse entanglement (entanglements different from the entanglement at the interval of wave crest), to this vehicle it is abnormal into
Row judgement.As a result, can be detected to the state being just abnormal.
The 2nd ＞ of ＜
In the 2nd, the functional safety sensor 32 of Fig. 3 is vehicle-mounted camera, and functional safety is vehicle-mounted camera with data
The data of taken camera video.It is configured to carry out A/D conversions to vision signal in addition, setting data transmission and processing device
And it is input to algorithm (algorithm), or vehicle-mounted camera is integrated with processing unit progress so that without using passing
Defeated path (cable), or compressed to carry out Digital Transmission.
In recent years, it proposes to have camera video for detecting and identifying (such as white line detection, signal identification, Hang Renjian
Survey, signboard identification, landmark identification, ranging etc.) or supplement (such as steering angle, speed etc.) for other sensors side
Case.In addition, for example also proposed the scheme for using multidirectional camera video as full-view camera.In order to accurately into
Row detection, identification and supplement, need to be transmitted the higher camera video of resolution ratio with higher transmission speed, for profit
With multidirectional camera video, need to be transmitted with the higher transmission speed camera video more to information content.
Such as transmit pixel be 720dot × 480dot, the camera video for the camera that frame per second is 30fps the case where
Under, need the transmission speed of about 166Mbps (=720 × 480 × Y/C (each 8bit) × 30).
Here, even if being configured to come by the data compression of the camera video to 1/40 and with the transmission speed of about 4Mbps
Transmission camera video, since the transmission speed highest of the buses such as CAN is also with regard to 1Mbps or so, can not also not reduce matter
Transmission camera video in the case of amount.In addition, though there are the transmission speed bus higher than the bus (such as FlexRay
(registered trademark), MOST (registered trademark), IDB-1394), but consider can not properly to other functional safeties handle data,
Other purposes processing data etc. are transmitted.
Moreover, in order to further increase functional safety, the number of units of the vehicle-mounted camera of each vehicle is inclined there are increased
To.If further, it is also possible to expect improving resolution ratio the biography for needing to carry out Gbps ranks moving body is identified in real time
It is defeated.
For example, as resolution ratio becomes 2.5 times of VGA (pixel is 640dot × 480dot), it is being to pixel
In the case that 1920dot × 1080dot, frame per second are transmitted for the camera video of the camera of 60fps, about 3Gbps is needed
The transmission speed of (=1920 × 1080 × RGB (each 8bit) × 60).
In addition, being H using the pixel number of horizontal direction, the camera that horizontal view angle is θ moves in the place of distance b
Body can use m=(b × tan θ)/(H/ along the Minimum sliding distance m (resolution ratio of horizontal direction) that can be measured when moving horizontally
2) it indicates.Specification as vehicle-mounted camera, it is contemplated that pixel number is 1920 × 1080, and horizontal view angle is 60 °, and lens are without mistake
Very.In the examples described above, H=1080, θ=60 °, therefore, Minimum sliding distance m in the case of b=100 be (horizontal direction
Resolution ratio) it is 0.109m (=(100 × tan60 °)/540).The value means that the resolution ratio of above-mentioned example is equivalent to VGA (pixels
For 640dot × 480dot) 2.5 times of resolution ratio.
For problem as described above, the upper monitoring unit 16 receive capabilities safety involved by the 2nd of present embodiment 2
With the data of camera video of data, the i.e. data without substantial reduction, and carry out pre-determined data processing.As a result,
Therefore the camera video that upper monitoring unit 16 can utilize information content more accurately can be detected and identify.
