Just put your function like this.

var mapCanvas = document.getElementById("map");
var myCenter = new google.maps.LatLng(51.508742,-0.120850);
var lat=51.508742;
var lng=-0.140850;
var mapOptions = {center: myCenter, zoom: 5};
var map = new google.maps.Map(mapCanvas,mapOptions);
setInterval(function()
{
ajaxRequest(map);
}, 5000);
